PROFESSIONAL
<£/?* ANIMATION! —

Now take advantage of "pencil
testing" your animation in the

| privacyof yourown home studio!

' With Cel Animator you can

preview scenes, polish your work
and know it performs the way you
envisioned.

UN-EQUALLED
VERSATILITY—

Cel Animator provides versatility that's unavailable
with film, or the expensive Lyon-Lamb type stop-
motion video tape equipment. With Cel Animator,
your drawings are stored on a computer disk so each
frame can be called up repeatedly and manipulated
within a sequence after being "shot" only once. This
is achieved because computer disk storage is
"random access," meaning; any information stored
on the disk can be called up at random, in whatever
order required, as often as necessary!

BREAK THE "SEQUENTIAL-
DILEMMA—

Tape and film are "sequential" and require you to
shoot a "cycle" over and over again until the required
number of repetitions are completed, or re-expose a
held drawing for many consecutive frames. Using
Cel Animator, however, you may simply create each
drawing once, and then create a list, identifying
each frame by number, and the program will call up
the stored frame from memory and replay it as often
as it is called lor, or in whatever order you specify,
and you can add or delete drawings. Essentially, the
program follows your "exposure sheet" for you!

Cell Animator

You can also experiment with your timing by simply
changing the display time between frames; il you
shoot a "pose test" you can adjust your timing
repeatedly without reshooting anything, then add
your breakdowns, re-time your delays and check
again. No need to add in-betweens until you've
line-tuned your pose test.

CONTINUOUS PLAY OPTION—

The program can also replay your sequence of
frames in a continuous loop, so you can si! back
and review the action repeatedly without having to
rewind and play a video tape over and over again,
or without ever having to wait for lilm to be shot,
processed, and edited.

SOUND SYNCHRONIZATION—

Cel Animator allows you to digitize your pre-
recorded sound track (dialogue, music or effects),
and replay them frame by frame; or select any group
of frames to replay, enabling you to locate and
identify sounds according to Irame number prior to
doing your animation drawings. Then, review your
pose test or completed animation synchronized with
your digitized sound track, and you can then print
an exposure sheet, vowels and consonants paired
with frame numbers.

INTRODUCE COLOR! —

Finally, if you own one of the many paint programs
available such as Photon Paint, you can paint your
pencil drawings right on your computer, and use
Cel Animator to replay them in full color, over any
background you create. It is also possible to send
your completed color scenes to video tape: thus
producing a full color animated sequence right in
your own home on your VCR or you can use Photon
Video's Transport Controller software,

COMPATIBILITY —

Photon Video Products are fully compatible with
most third party art. animation and rendering
software systems-

TRANSPORT CONTROLLER —

This module allows you to take your animations
frame by frame to video tape, by way of popular
Irame by frame controllers such as Lyon Lamb." 1

Yes. that is a solar eclipse nj sorts happening on
this month's cover. Why? Birau.se powerful per-
waul computers like the Amiga are taking over
the scientific/graphics workstation market from
the specialize/! workstation systems makers such
ns. right. Apollo and Sun! Comparable comput-

Great expectations.

AmigaWortd was ready for the beach this month, but it rained. Damned
New England weather; there'll be a foot of snow again before you can say
"Legs Diamond" (Linda, Senior Editor/News-and-Flooze gal, left center), or
"flickerFixer." Which reminds us: we did spend some considerable time this
month (see the feature article and the Reviews) on a product to help you
beat the hl-res Interlaced blues. Our writers loved It; our Reviews man said
"it's leagues ahead of sunglasses." Weil, at SS9S it should bel We spent
only about S100 to outfit the whole staff, including the Teddy Bears, who
were miffed because they were supposed to be on last month's cover. And
yes, Bob's dog Mae— to the left of Bob, the ramblin' wreck of Amiga Tech,
right. All to show you a cheaper, and more fun, way to do it.

We hope the sun is shining where you are — and, by the way. get in-
volved in our Summer '88 Treasure Hunt and win some good stuff. (Before
Barbara does; she's our Reviews/Fashion Editor, right center— Barb made
her mother change her name and move to Peoria, Illinois, so she could
send in a phoney correct solution.) That spacey character in the center rear
is Guy, the person responsible for AmigaWorld. The rest of us are Dan
(senior word warden, behind the potted palm), Shawn (head manager-type
and video mogul, supporting "Legs"), and, of course, the bears. The per-
son who orchestrated this whole scene is Roger Goode of our design staff.
The photographer would rather keep his name out of it — but, what the
heck, Frank Cordeile did it and he should have known better!

6 Augii.st 1988

I'VE BEEN DOING a lot of
traveling lately — Hannover,
Washington, Atlanta, Kansas,
Florida, New York — and I'm
approaching a slate of perma-
nent jet lag. Mv kids don't rec-
ognize me anymore, and
hotels are beginning to feel
like home. 1 hope you all ap-
preciate my efforts and don't
think that 1 have a glamorous
joh. It's a lot of fun, hut some-
times I feel envious of mall
janitors. All they have to do is
shamble about, sweeping up
cigarette butts. They don't
have to travel, make speeches,
or write editorials.

These past few months have
been exciting for Commodore
and the Amiga. New products
have been announced and
talked about. But when are all
these things going to be avail-
able? When are thev going to
be real? I heard a number of
questions like those when
Commodore announced the
A2000. Should I wait before
buying something because a
newer version will be coming
along soon? Should f start
drinking about trading in my
A2000 for an A2"i00? 1 don't
think so.

First, there is no guarantee
that a particular new product
will ever be for sale. Second, I
wouldn't hold my breath on
any of these new Amiga prod-
nets. Some will be ready bv the
end of the summer, many will
be ready sometime in the fall,
and some won't be ready until
1989. Which ones will show up
first? 13 will probably be the

first. 1.1 and the new chip set
might become HIS*) products.
The A2500s are just A2000s
with extra hoards and mem-
ory, so if you own a 2000, you
already own a 2500 chassis.
flu- I i ansputcr is probabb
the longest shot of the bunch.
I have my doubts about the re-
lease dates (and quality) of the
two video boards, so if vou
need one, don't wail for Com-
modore. The new monitors de-
pend on other manufacturers,
so they are anybody's guess.
I'm sure there will be an
Amiga 3000 someday but I'm
also sure that eventually there
will be a manned mission to
Mars.

Commodore is making an
effort to make everything up-
gradable in the Amiga line.
The A2000 can be turned into
an A2500. Most of the soft-
ware will work on all Amigas.
Operating system upgrades
are possible on all models. It
may cost more to upgrade an
older Amiga, but that's life.
Eventually you will have to
buy a new system or scrap
some of your software — that's
the cost of progress.

We will continue lo tell vou
about everything thai Commo-
dore is working on for the fu-
ture, but keep in mind that
until a product shows up on
store shelves, it isn't real. If
vou need something now. bu\
it now.

Taming Agnus

FRED KUHLMAN'S LETTER

in the May issue ["Fat Agnus
On The Loose," Repartee, May
'88, p. 10] was a lifesaver. When
I first purchased my Amiga 500
six months ago, it came out of
the box with exactly the same
problem that Mr. Kuhiman de-
scribed. I returned it to my
dealer, who told me that he had
no idea what the problem was.
I received a new computer.
which worked well until just re-
cently. Then, the same problem
recurred. I was frustrated to say
the least. I had the machine
packed and ready for the re-
turn trip to the dealer when
your May issue arrived with Mr.
Kuhlman's timely letter. I
quickly unpacked the machine
and applied pressure to the Ag-
nus chip and the problem was
corrected. Since then, I haven't
had any problems with it.

Well-Worded

GL'Y WRIGHT HAS had some
solid gripes in his Zeitgeist
column for the past few
months, and most of us have
been in agreement with him.
However, he hasn't mentioned
the worst plague of all — the
horrible state of written
documentation.

Have you ever driven into a
strange city, stopped the near-
est guv on the coiner and
asked him how to get to Main
Street? He gives you a ten-min-

ute monologue, you thank
him, drive away, and then turn
to your wife and say, "Jeez,
what did he say?" Your wife
tells vou she couldn't under-
stand a word of it either.
That's the way I feel when I
plunk down a hundred bucks
for a program and, with the
aid of Five friends, can't figure
out what the manual is trying
to say.

Don't sav clear and concise
instructions can't be written.
Thousands of us have built
Heathkit computers that were
totally new to us. If cake reci-
pes were written like software
documentation, no one would
eat cake.

New Motherboard

AT THE RECENT NCGA
show. I expressed to Paul Hig-
ginbottom, Commodore's
Amiga Products Manager, my
concern about the future of
the Amiga 1000. I am worried
about the much talked about
increase in chip RAM to 1MB
or more in the A500 and
A2000. I forsee software that
will require this and that will
not operate on the A 1000. 1
suggested that Commodore at-
tempt to make an upgraded
motherboard for the A 1000
that would allow us to have
the expanded capabilities of
the other machines, yet still al-
low us to use all of the periph-
erals, such as internal RAM
expanders, that we have in-

vested in during these past
two and a half years.

Unfortunately, Mr. Higgin-
bottom was not impressed
with the idea. He feels that a
new motherboard for the
A 1000 would cost as much to
produce as a complete A500
and would not have a large
enough sales potential to jus-
tify the costs involved. He did
Finally agree to consider the
idea if we, the A 1000 owners,
could prove that there is
enough interest in such a
product.

Now it's up to us. Send let-
ters to Paul Higginbottom and
Irving Gould, Chairman of the
Board, at Commodore. Get up
a petition at your local users
group, post messages on the
BBSs and commercial services.
Don't be left behind and lose
your investment in those ex-
pensive add-ons for the A1000.

of 16-bit minicomputers, while
the VAX line consists of
newer, 32-bit machines. Both
lines are made by Digital
Equipment Corp. (DEC).

These machines often serve
as microcomputer network
host systems and database

servers. In fact, Apple recently
signed a contract with DEC
that establishes the Mac as a
business workstation for use
with VAX systems. Since all of
the networking protocols are
or will be published, this
would be a great area in which
to develop Amiga applications
that could work with VAX sys-
tems. Macintoshes, and Mac-
VAX applications.

I AGREE WITH Guy Wright

[Zeitgeist. June '88, p. 8] that
"U.S. manufacturers should be
more considerate of Amiga
owners overseas." I have pur-
chased a wide range of soft-
ware, and the user support has
been non-existent.

I have Filled oin registration
cards to receive information
about upgrades and new prod-
ucts, hut (he result of my ef-
forts has been nothing! This
applies even to products like
DeluxePrint (Electronic Arts)
and DigiPaint (XewTek), of
which new versions have been
released. Do software compa-
nies have the insular attitude
that Amigas are only used in
the U.S.?

Artists' Showcase

VIDEO ANIMATORS AND computer graphics artists can now take advantage of a new way to display their talents. The
Avant Garde Network (AGN) of Mount Pleasant, Michigan has opened of a graphics/animation showcase, giving
individuals, groups, and manufacturers a chance to show their works and their wares.

Artists can submit their videos and slide shows to AGN, which distributes television programming to broadcast and
cable operators, and AGN will consider them for possible broadcast on the showcase programs. "There really has
not been an open channel available for these artists to show their stuff," said an AGN spokesperson. In the past,
computer trade shows and video fairs were the only way for the public to get a look at the work of computer artists.

Artists will receive full credit for their efforts, and each display of artwork will be captioned. Manufacturers of the
equipment used in producing the art will also be credited. Awards for outstanding work will be presented bi-monthly.
Computer art from all levels of technical sophistication will be considered, and there are no submission fees. Artists
should submit their work on S-VHS, VHS, or a /i-inch videotape to Avant Garde Network, PO Box 919, Mount Pleasant,
Ml 48604. Submission of a tape authorizes the network to broadcast, cablecast, or satellite telecast the artwork for
up to one year from the date the material is received. AGN also reserves the right, if necessary, to edit artwork to
accommodate their programming schedule. — SL

Show Hopping

AFTER A WINTER of hiberna-
tion, the Amiga awoke with a
roar this spring and attended
three shows in two and a half
months. Commodore and the
Amiga jetted from the Han-
nover Fair in Germany (see "For-
eign Correspondence," p. 12 in
the June '88 issue ot'AmigaW'orld)
to the Amiga Developers Con-
ference in Washington, D.C. to
Comdex in Atlanta, GA, leaving
a trail of press releases behind.
Beyond what was said you could
watch a deft display of slight of
tongue. How products and
promises were presented de-
pended on where you were.

The Amiga Developers
Conference

In April, the people behind
the programs and peripherals

invaded I.' enfant Plaza Hotel
for the Amiga Developers Con-
ference, three days of intensive
seminars, panel discussions,
and speeches. Besides the usual
hard-core techie seminars, ihis
year's conference offered semi-
nars on public relations, mar-
keting, and selling products
abroad. Most of the attendees
(which for a change included
company presidents and mar-
keting directors) agreed I hat
these seminars were a worth-
while addition to the agenda.

Commodore gave more de-
tailed information about die
products announced al Han-
nover and added a few new ones
to the list. While the company
openly discussed its products
and plans, the general tone was
cautious. Version 1.1 of ihc op-

WAugusi I9SS

crating system will feature "ma-
jor revisions" to Workbench and
is scheduled to coincide with the
new chip set. To display the won-
ders produced by the new chips.
Commodore Is working on bi-
sync monitors (15 and 31 MHz)
that will support the non-inter-
laced modes. There was also
some talk about a l'VA (Profes-
sional Video Adapter, a combi-
nation genlock and frame
grabber) board for the A2000.

Commodore was careful to
point out that all the new prod-
uct announcements were not
finalized and things may change
between now and when (or if
ever) they are finished. Because
the products are in the early
development stages, listeners
had to take the supplied specs
with a few shakers of salt. The
mere existence of specifica-
tions, however, showed the de-
velopers that Commodore had
progressed beyond the siage
of "wouldn't it be nice if we
had a. . ."'

On the marketing and pro-
motion side. Commodore's
plans for the Amiga are still
pretty vague, but the company is
beginning to pick a few direc-
tions. Vertical markets, educa-
tion, and video were most fre-
quently mentioned as targets.

The overall mood of the De-
velopers Conference was opti-
mism with substance. Attendees
came away with a strong impres-
sion that the Amiga line is where
Commodore aims to make its
money in the future. The con-
ference was smooth and well
run, which indicated that Com-
modore is gclting more serious
about their developer support,
for a change, developers not
only enjoyed themselves but got
the important material and in-
formation they needed as well.

Comdex

The Amiga's prescence al
Comdex also took a change for
the better this spring, although
it was slightly off the beaten
track. Commodore's booth at
the Atlanta show was always
crowded, but the real action was
across the street.

On the first day of the show.
Commodore rented three large
function rooms in the Omni In-
ternational Hotel just across
from the main convention cen-
ter. At the morning press con-
ference in the first room, Dr.
Henri Rubin, Commodore's
Chief Operating Officer, gave a
very stiff talk on Commodore's
plans to release its Unix board,
68020 board, 80286 AT board,

2024 hi-res monitor, 2350 PVA
board, as well as the improve-
ments in 1.3 and plans for the
enhanced chip set. After Han-
nover and the Developers Con-
ference, the Comdex press
conference was a lei down.
Commodore seemed to fall back
into the hype of "the Amiga is
a wonderful computer, honest."
The company skimmed over the
new product announcments
and spent most of the time re-
launching the Amiga.

The conference was more in-
teresting for what il did nol men-
tion. Commodore did nol
describe the A2500s, (he bi-sync
monitors, the Transputer, (be
A500 hard disk controler, 1.4, or
even a lot about 1.3. The main
reason for the omissions was
that Comdex is where compa-
nies make announcements
about products that they are
pretty certain will be releasee!
(companies that have had trou-
ble with the Federal Trade (lorn-
mission that is). While ibis does
not mean that the A2500s, mon-
itors, low-end genlock, and so on
are never going lo ship, it does
mean that Commodore was nol
sure enough about their config-
urations, dates, or viability to
talk about them at Comdex.

The second room held the

dealer luncheon and confer-
ence. Commodore turned the
third room into a mini-exhibi-
tion hall for developers, provid-
ing over 75 Amigas, Developers
finally had a location thai was
big enough to properly demon-
irate their wares to dealers, dis-
tributors, and the press.

There was plenty to demon-
strate. Future Touch showed off
an Amiga touch screen; ASDG
had a do-evcrvthing board for
(he A2000; Mimetics ran a 3-D
modeling program; Epyx
played a handful of new games;
Haitex Resources proudly wore
their high-tech 3-D glasses; Dis-
covery Software rode their wave
of hot products, and on and on
(for complete descriptions see
What's New? in this and upcom-
ing issues).

Not only were there three
limes the number of Amiga de-
velopers at this years Comdex
than at previous shows, bin just
about all of them were in one
of the three rooms on the first
day. In the shadow of an IBM-
obsessed, somewhat slale show.
Commodore managed to prove
that the Amiga does exist, il is
big enough to attract some at-
tention at Comdex, and Com-
modore can occasionally do
things right, — GSW

Hints, tips, and techniques
from your fellow Amiga users.

De-Arc De-Zoo in RAM

TRY THIS METHOD for extracting Arc

or Zoo files. When downloading from a
fiBS or an on-line service, download the
file to RAM (if yon have enough mem-
ory). Then, when done, de-Arc or de-Zoo
die file in RAM. After you have ex-
tracted it, run it, and if you like it, copy
the file(s) to a disk with a DIR utility or
the regular COPY command. If you
don't like it, simply warm hoot the sys-
tem, and it's gone.

Ryan Kncharshi
Fairborn, OH

Editor's Note: You might want to save the Arc
or Zoo file to a temp file before you run it.
That way, if something goes wrong, you still
have a copy of the program.

C Commands on
5.25" Drives

I FOUND A good use for the 5.2")" drive
in the quest for more working RAM
space. If vou are using a RAM disk for
commands to free up your 3.5" disk
drive, do basically the same thing to
your 5.25" drive (you don't really need a
subdirectory called C), then ASSIGN
SYS:C to DF2:. Or, you might want to
use it for an add-on to your SYS:C direc-
tory, as I do. Put extra commands, such
as DIRUTIL or other public-domain
commands (or things like TxED), on the
5.25" drive and put a PATH command
in your startup sequence to direct
AmigaDOS to the extra commands. It is
by no means fast, but it docs give you a
place for all that stuff that doesn't fit on
your Workbench. (Note: This only works
under AmigaDOS 1.2.)

To Mr. Al Willen of Riverdale, NY,
who had the tip about the 5.25" drive
stealing SOK [Mors d'oeuvres, July/August

"87. p. lb]: It's true, but if you are going
to turn it on no matter what, then you
might as well use it for something. Right?

Steven Johnston
Lacey's Spring, AL

PATH Speedup

I HAVE SEEN many tips from Amiga-
World readers aimed at speeding up the
execution of AmigaDOS commands and
freeing the user from the need to have
the Workbench disk inserted at all times,
but I haven't seen the following method
mentioned.

This method speeds execution while
conserving RAM. The key is the PATH
command, which controls the order in
which AmigaDOS searches directories
for commands. (This command is avail-
able only in version 1.2, but I'm assum-
ing anyone who is interested in speed
has made the switch.) Insert the follow-
ing lines into the startup sequence:

makedir ram:c

path add rami
copy exopy to ram:c
copy c:deletc to ranix

This makes AmigaDOS check in RAM
for commands before searching on the
disk. The only restrictions on the place-
ment of these lines in the file is that the
MAKEDIR and PATH commands should
come before any other PATH commands
in the file. Copy only the commands you
use most often, with COPY as the first,
to speed things up. With the proper
choice of commands, you can eliminate
over 80% of your disk access for com-
mands, and only use up 25-35K of pre-
cious RAM. Also note that this works just
as well for any executable file you use-

often, not just AmigaDOS commands.
The partial RAM DOS will be activated
after you do a warm or cold reboot.

John Johnson
Ithaca, NY

Editor's Note: I'm not sure if we have pub-
lished this tip in the past, hut even if we have,
not everyone has all of our back issues.

Faster Marauder II

ONE Of THE most noticeable features
of Marauder II is its scrolling rainbow
background. This background creates an
impressive display, but is unnecessarily
taxing on the CPU. You can speed up
the disk backup process significantly by
pushing the Marauder screen behind the
Workbench screen. Do this by holding
down the left Amiga key and pressing
the X key, once the process has begun.
You will hear the drive(s) speed tip as
soon as the Marauder screen is hidden.
To return the Marauder screen to the
front, hold down the left Amiga key and
press the M key. With a single drive and
1MB of RAM. 1 was able to reduce Ma-
rauder's backup time from -1 minutes, 12
seconds to 2 minutes, 55 seconds (in ana-
lytical mode, verify on).

Unstuck With ASSIGN

I OFTEN USE the RAM: disk to store my
frequently accessed commands. If you
delete the commands stored on RAM:
before reassigning C: to SYS:C [see
info.phile, p. (53. in the April '88 issue of
AmigaWorld], there is a wav to get un-
stuck. Place the disk you booted with in
any drive (let's say DFO:). Then enter the
following front the CLI:

DFOx/assign c: DK0:c

This allows access to the ASSIGN com-
mand by specifying the complete path.
Now you have access to the commands
in the C directory of your boot disk.

This technique can also be used to
force AmigaDOS to search only lite spec-

ified directory when looking for a
command.

Quicker Startup

IF YOU ARF. used to entering (he date

try this. Rename votir startup sequence
as "Rest", then create a new startup se-

This lets you enter the current date

Cure for Ailing Mice

I RECENTLY DISCOVERED a mouse
cure that may be helpful to others. When
I clicked on an icon, it acted as if I had
double clicked it. and when I used sizing
gadgets, they wouldn't always work

smoothly, It was as if the computer was

receiving the wrong number of mouse-
button clicks, I opened the mouse to see
if it was a dirty switch.

To do this, turn the power off and dis-
connect the mouse from the computer.
Remove the two screws on the bottom
where the cable comes into the mouse.
This will expose two wafer switches. The
switches consist of a dome-shaped piece
of metal with a dimple in the center held
over a C -shaped printedcircuit trace
with tape. The dimple of the upper con-
tact should be centered so that the
mouse button hits it — mine was off cen-
ter. (You should notice marks on the
tape where the mouse button is making
contact.) I removed the tape, recentered
the contact on the trace and replaced
the tape. I haven't bad any problems
with misinterpreted mouse clicks since.

Keyboard Controlled
Sequencer

Music to a MIDI maestro 's ears.
By Bob Lindstrom

THE DOCTOR IS in, and suddenly
professional MIDI music is alive and well
on the Amiga. Dr. T's Keyboard Con-
trolled Sequencer (KCS) turns the Amiga
into an outstanding MIDI-controlling
computer, whether you're producing
your first album or slapping together a
musical demo for the local users' group.

At the outset, the Amiga was troubled
by some faulty attempts at MIDI prod-
ucts. In KCS though, Amiga musicians
have a recognized industry-standard
MIDI sequencer.

For those not familiar with MIDI (Mu-
sical Instrument Digital Interface), a se-
quencer turns your computer into a
multi-track tape recorder, recording
notes played on a synthesizer or entered
one by one in a step-time editor. You can
then cut and paste those building blocks
of rhythm, harmony, and melody into a
fullblown composition. Sequencers will
transpose keys, alter rhythm, and recom-
bine individual parts too, and if your
fingers betray you with a few clinkers,
you can edit individual notes and fix
your flubs. Once your masterpiece is
complete, the sequencer plays it through
your MIDI instruments. With a few syn-
thesizers, it's like having a backup band
on 24-hour call.

KCS is a 48-track sequencer with real-
time recording, a step-time note editor,
and the ability to create up to 128 sepa-
rate sequences. It works with any MIDI
port that attaches to your serial port. Pro-
gram operation is swift and efficient, mak-
ing the most of the Amiga's processing

muscle. In addition to the cut-andpaste
functions that make KCS the equivalent of
a musical word processor, the program
has dozens of advanced features, detailed
in the 278-page manual. Virtually all desir-
able MID! functions are included: the
ability to quantize during or after record-
ing, punch in/out with an undo option,
audible and visible metronome, song
pointers, sync to internal or external
clock, and a separate program to convert

Open Mode's flexibility incites creativity.

KCS files to the MIDI file standard thai
several other publishers use.

With large windows to display infor-
mation, KCS is terrific for the MIDl-ori-
ented composer or performer. But KCS
displays music only as MIDI data; it does
not deliver standard musical notation.

The Doctor Will
See You Now

Versatility is the keynote of KCS; this
program allows you to write music the
way you want to. Three systems are avail-
able for composing.

The Track Mode is a 48-track tape re-
corder with continuous overdub. Just
choose a tempo and MIDI channel, and
the program records synthesizer input in

real time. The length of the first re-
corded track determines the length of
subsequent MIDI tracks. If the initial
track is eight measures long, later tracks
will be eight measures as well. Even
within this seeming limitation, KCS of-
fers versatility. When using continuous
overdub, the Track Mode is prepared to
record a new track the instant one is fin-
ished. If you want to record a 24-mea-
sure solo, KCS will create three
consecutive eight-measure tracks to con-
tain the entire piece.

Moving to the Open Mode, a highly-
flexible environment for joining and al-
tering fragments, you can combine those
tracks into one continuous solo. You can
then go on to produce entire scores,
writing control sequences that trigger
other sequences. KCS allows you to cre-
atively alter sequences to add variety to a
composition; you can transpose and
mute sequences, change tempos instantly
or gradually, transmit patch-change in-
formation to MIDI instruments, and
even add an element of randomness in
pitch and rhythm. The RA command, for
example, will make a random choice
from a list of specified sequences.

When you first write a control se-
quence, you will probably instruct the
computer to initiate a group of se-
quences and wait until all are completed
before moving to the next set. With ex-
perience however, you can create an
Open Mode control track that begins se-
quences at any specified point, and then
lavcr and stack fragments at will. While
this technique is more painstaking, it
provides the ultimate in flexibility.

Song Mode offers a less complex way
to assemble music in verse- and chorus-
like structures. Even beginners can
quickly assemble scores in this manner.

In every mode, KCS provides a full ar-
ray of editing options. You can accom-*-

plish virtually any MIDI track or
sequence alteration, from simple note
correction to adding crescendo/dimi-
nuendo and special effects. Best of all
when you finish an edit and hit the Re-
turn key, the cursor goes precisely where
you'll most likely need it. Obviously the
developers heeded MIDI users'
suggestions.

A General Practitioner

The numerous keyboard and mouse con-
trol options also reflect an effort to
accommodate the work habits of com-
posers. The program eschews pull-down
menus and puts most features on screen
where you can access them via mouse
clicks or keystrokes. Unfortunately, key-
strokes are rarely logical, so beginners
will be glued to the manual. Frequent
use will teach efficiency though, and
help screens are available for some of
the more complex operations.

As a nod to multitasking, KCS in-
cludes menu items that transport you to
Workbench or a new CI. I window. From
that point, you can open as manv addi-
tional programs as RAM allows, You will
not however, want to multitask while lis-
tening to a sequence. The time-sensitive
nature of MIDI dictates that rhythmic
glitches will occur if you run another
program while replaying.

On start-up, the program asks how
much memory vou wish to allocate to
the program. A 512K Amiga has room
for a maximum 16,000 note events
(which Dr. T's defines as a six-byte en-
try). One megabyte of RAM will accom-
modate aproxhnateh 1)0,000 note cents.
and three megs can store about '500,000.
To bring these totals into perspective, I
composed a four-and-a-half-minute piece,
making extensive use of a few tracks. It
occupied only -IK of RAM. Unrestrained
use of a pitch bender or lengthy multi-
tracking will eat memory quickly, but
with a little compositional tidiness, the
16,000 note events of an utiexpaiuled
AfiOO can go a distance.

I was surprised to discover that the
manual covers both the Amiga and Atari
ST. While otherwise good, the documen-
tation is geared for the Atari. Where ref-
erences are made to the seven keys not
identical on the ST and Amiga key-
boards, the manual cites Atari labels. A
chart is provided to translate the names
for Amiga users. Notes, explaining spe-
cial Amiga applications, are sprinkled

throughout. Dr. T's promises an Amiga-
specific manual shortly, however.

The keydisk c< '\protection scheme is
no more irritating than others like it, but
there is one fault. When booting a KCS
copv, the program requests insertion of
the original disk. If you replace the
working copy with the original, the drive
spins, the screen goes blank, and the
program seems to hang. In fact, KCS is
waiting for reinsertion of the working
copv. Because there is no requester to
explain the situation though, you might
incorrectly conclude that the program
has failed.

I was able to crash the program only
once — by trying to write to a reserved se-
quence (KCS saves a few sequence posi-
tions for its own use). The system
required a warmstart for recovery.

Final Diagnosis

The ultimate test of a musical tool is
whether it stands in the way or makes
creative juices flow. KCS freed me from
constraints imposed by other Amiga
MIDI programs. In fact, preparing this
review took much longer than expected
because each writing session turned into
a new piece of music. KCS creates that
kind of inspirational excitement. Dr. T's
is now working on a significant feature
they plan to add lo 1.6; the ability to
play through the Amiga's speakers. This
would effectively provide a four-voice
multi-timbral synthesizer, and allow you
to get started with only one external syn-
thesizer. It looks as though KCS will con-
tinue to be Dr. Feelgood for MIDI
composers at every level.

Source Level Debugger

The C programmer's pain reliever.
By Jim Fiore

I THOUGHT I'D be sprinkling printf()
and ifdef DEBUG throughout my code
till raisins rule the planet. Fortunately

ihough, the folks at Manx Software have
provided a C interpreter with an interac-
tive editor for spotting errors and mas-
saging data: the Source Level Debugger
(SDB).

A full-featured C source-code debug-
ger, SDB allows you to trace through a
program — line by line, function by func-
tion, or however you desire — while it
executes. You can examine or alter vari-
ables and constants at any point dining
the process.

SDB, which tips the scales at 90K,
works only with the most recent release
of the Manx Aztec C compiler; version
'Mi (you can't use it with the Lattice com-
piler, cither). The program disk contains
a useful demo, actually three separate-
units, each of which walks you through a
debugging session with a different pro-
gram, via a command file.

A File to Debug

To use SDB, you must create a debug file
(using the Aztec compiler), by compiling
and linking with the SDB options -n and
-g, respectively. Unfortunately, you must
recompile older (prc-3.6) object files in
order to create debug files. The small in-
crease in the compile/assemble/link cycle
time will vary with program size. I wrote
a program that opens a screen and two
windows, attaches a short menu, sets up
a variety of boolean and proportional
gadgets, and does the typical IDCMP
processing. The normal cycle took ap-
proximately 2 minutes, 22 seconds, and
produced an executable file of 18656
bytes. With SDB, the cycle took an extra
16 seconds and produced a debug file of
20032 bytes (the executable size was the
same).

Once you've created the .dbg file, you
can start SDB. The easiest way is to enter
SDB followed by a space and the pro-
gram name into the CLI. If your pro-
gram uses command-line arguments, list
them after the program name as usual.
Options let you start in assembly mode,
set up colors, and more. Invoking SDB
opens a full-size, three-part window. The
uppermost section shows your C source,
and the bottom portion displays SDB
output; both have scroll bars and arrows
for easy viewing. Separating these parts
is a single command-entry line, which
you can reposition. Moving the com-
mand line up shrinks the source file seg-
ment and expands the output section,
and vice versa (all proprotions remain +■

[tie same). After creating llie window,
SDB searches though the source file,
finds the part with main( ), loads it, and
stops at the main( ) entry point. SDB
numbers each line of source, and high-
lights the present/active line (the one
about to be executed),

BEGIN DEBUGuine

A variety of commands will start the de-
bugging process. If you have used
Manx's assembly debugger <db), main of
these will be familiar. With the single-
step (s) option enabled, SDB will execute
the present/active line and halt at the
next line. If the present/active line hap-
pens to call to one of your own func-
tions, SDB will step into the source for
that function. The t command operates
the same way. but treats your function
call as a single line.

To execute a segment of code, use one
of the g (go) command variations. Essen-
tially, go sets a temporary breakpoint; if
you specify a line number or function,
SDB executes until it reaches that point
or an associated return. You can also set,
clear, display, and reset permanent
breakpoints. The breakpoint-set com-
mand lets you specify skips (the number
of times SDB is to bypass the [joint be-
fore breaking), and indicate a list of SDB
commands to be transacted upon the
break. Using this feature, you can zip
through the middle 498 iterations of a
500-count loop. The c command centers
the present/active source line in the dis-
play, while df shows you the contents of
the source file. A string-search command
is helpful for locating every occurrence
of a specified function.

When SDB comes across an illegal in-
struction during execution, it stops and
displays the contents of the Amiga ad-
dress and data registers. If your program
does something very bad (like closing a
window after closing its screen), Mr.
Guru will visit; running a program in
SDB doesn't insulate you from fatal
errors.

SDB provides a number of memory-
display options. You can examine any
memory location in hex and modify the
value, and display auto variables and all
code and data symbols. SDB also lets you
evaluate normal C expressions right on
the command line. For example, vou
might have SDB evaluate ptr= array_of__
struct[0] + 1 in order to check the ad-
dress of the second structure in the array

(yes, SDB does pointer math). You can
redirect the input/output of the SDB
command line to another file, allowing
for convenient macro definition or a de-
bug session log.

JiTTERBUGGING

Perhaps the most attractive feature is the
fortnatted-print command. You can print
just about anything including arrays and
structures. If my_window is a pointer 10
a window structure for instance, by issu-
ing a single command you can print all
the fields in a structure, with their labels!
You can also directly investigate strings.
If you'd like to sec the starting address
of the string in element [0] of an Inttii-
I'ext array called my_text, you might en-
ter p my_iext[0].Itext. This will produce
the response unsigned char *ITcxt =
0x0, . .some address. The command p *my
text[l)].ITexl will yield the ASCII value of
the first character. The real fun begins
when you use ps instead of p— in the last
example, the output will be the actual
string!

There are a few inconsistencies in the
print command. I.et's say you've declared
an array of integers called color_tablc.
As expected, if you enter p color_ta-
ble[0], SDB will give you the value of ele-
ment 10] (by the way, you can get this in
either hex or decimal, and it's also possi-
ble to print in octal, or convert floats
and doubles), and entering p &color_
table[0] produces element [0]'s address.
But when you enter p color_table (note
that without the subscript this indicates
the head of the array), SDB delivers the
value of element [0] instead of the ex-
pected address. Evaluating with c color_
table will yield the address, as will prim-
ing or evaluating color_iable. strangely
enough (the exact output is (*color_ta-
ble)[()] = . . .address). While you might
think this is SDB's way of indicating a
pointer to a pointer, if you go back to
the preceding example using mv_text,
and insert p my_text[0],IText, SDB re-
sponds: unsigned char **ITexi = . . .
address (note the **), just as it should.
I've stopped referring to arrays in this
fashion with SDB; after all, you can get
the desired results in other ways.

Other features include a nice on-line
help facility, the ability to move up and
down the call frame (to see who called
what and to investigate local variables
that would otherwise be hidden), and the
command-line history. SDB also has pro-

visions for testing device drivers and li-
braries. The short manual is logically
laid out and contains most of what you
need to know. Experience with Manx db
may quicken the starting pace.

My favorite trick is using SDB to op-
timize the look of windows. With the
help of SDB's memory modify com-
mands, I can open a window, verify posi-
tioning, close the window, modify the
positioning values, reopen the window.
and so on. When I finally get the values
I like. I just jot them down, and stuff
them into the source. This may not be
the quickest route, but it's faster than
guessing and recompiling, and it saves
the cost of a layout program.

SDB is a valuable development tool
and instructional program for new G
programmers — especially considering its
price. SDB may not be the perfect Amiga
C debugging environment, but it comes
much closer than anything else I've seen.

Photon Paint

HAM it up.
By Roger Goode

AS A PROFESSIONAL artist, I can be
very demanding of the workability of a
graphics program. Photon Paint, A full-
featured Hold-and-Modify (HAM) paint
program, is simple to learn and use. Pho-
ton's developers had the good sense to
style their interface after the user-friendly
DeluxePaint II (Electronic Arts); many
tools operate similarly, and some key-
stroke commands are the same. For those
not familiar with DeluxePaint II, or even
with the Amiga, the excellent manual
makes no assumptions about your back-
ground. It reads like a primer for the nov-
ice Amiga artist; tutorials guide you
through the most important features, and
each menu entry is described clearly and
concisely. Even experienced users will
find it a valuable reference tool.

disk (which supports overscan and the
European PAL standard) offers a lull
complement of tools, a few that are
unique, and all of which operate in a re-
fined manner, lite 011 -screen toolbox lias
most of the hastes — a variety of standard
brushes in different sizes, freehand draw,
straight lines, curved lines, outline and
filled shapes, color fill, fonts, a magnify-
ing tool, and the all-important hrush-
grabbing tool.

The toolbox itself occupies a fairly
large band across the top of the screen.
While you can easily move it up or down
and toggle il on or off, a smaller toolbox
would not be as likelv to hinder the flow
of creativity. 'lb the program's credit
though, the tools operate behind the
toolbox. So, if you begin a circle whose
dimensions go bevond the boundries of
the toolbox, you can draw over the
box — without niggling i[ off — and still
achieve a complete circle.

While most standard tools behave as
expected, there are a couple of excep-
tions. The color-fill tool works in three
different wavs. flood fill, as usual,
changes all adjacent pixels of a given
color to the newly-selected color. Free-
shape fill similarly floods an area out-
lined by hand. The unique Boundry fill
covers all pixels within an area bounded
by a specified color.

The magnification tool is about the
best I've seen. You can position the intui-
tion-style magnification window any-
where on the screen, and size it to any
dimension from flea-hair close right up
to full-screen si/e. Gadgets in the win-
dow's borders let von size, scroll, and re-
position the image, and quicklv set
minimum, medium or maximum magni-
fication with a click of the mouse.

Another neat and unusual device is
the 1'ix tool; it gives your work a mosaic-
like, "pixelized" look. You can change
the size of the pixel blocks to suit your
needs.

Mixing Paint on the Palette

The most important element of a HAM
paint program is the ability to manipu-
late and display all of the Amiga's 4096
colors. Photon Paint's well-conceived pal-
ette holds an impressive 6-1 basic colors
for straightforward operations, and an
extended palette for heavy-duty color
mixing and selection, the expanded pal-
ette displays three Digi-Paint (N'ewTek)
stvlc squares thai represent sides of a 3-D

cube containing all 4096 colors. As vou
move the cursor around in one box. the
display in all three changes to reflect the
field you're in. You can select the (if
colors for your palette bv clicking in
these boxes, or by manipulating the RGB
(Red. (been, and Blue) and HSV (Hue,
Saturation, and Value) sliders. Also in
the extended palette are gadgets for
copying and swapping colors, and for
creating color spreads. As you make
changes to (he palette, none of the
colors that are already part of the image
are affected.

Until now, working with HAM pictures
has invoked fighting with the odd shad-

A brush Is wrapped to a sphere.

owing/ft iitging created bv the juxtaposi-
tion of some colors. Photon Paint
endeavors to minimize this effect, and
while the program does not eliminate
the problem, il comes close. I he Amiga
holds 16 colors, which are the basis of all
4096 shades, in 16 registers. Using these
base colors, the program attempts the
best transitions between those used on-
screen. The default palette consists of a
carefully-chosen range that should pro-
vide the best results in mosi cases. Pot-
paintings that lean heavilv to one part of
the spectrum, the default palette may
not work, so Photon Paint provides op-
tions for setting your own base colors.
You can conveniently arrange these
across the top of the palette, and copy or
change them at any time (the manual
shows you how to achieve optimal
results).

Normally, the program subtly modifies
chosen and on-screen colors (only the
base colors remain unaltered), thus en-
abling itself to use more than the stan-
dard 32. The Exact Color option lets you
override this, however, and gives vou just

the color you've chosen. I'd recommend
using this option sparingly though, be-
cause it can induce fringing in surround-
ing colors. The Base-color menu lets vou
choose base colors from the current
brush or the alternate screen, so vou tan
integrate material from other pictures.

Brushing Up on Basics

Photon Paint's most impressive features
are under the Brush menu. Here you'll
find all the basics — brush Hipping, resiz-
ing, bending, rotating — that you lake for
granted. Keep in mind though, this time
they apply to Hold-and-Modifv mode.

The Tilt feature is much like Oeluxe-
Paint's Perspective mode: il even involves
(he numerical keypad. Tilt has a pleas-
ingly intuitive feel, however. With a
brush attached to the pointer. Tilt mode
presents a hollow box that you can repo-
sition on various axes with the mouse.
It's easy to envision the outcome as vou
change planes and positions.

Using the brush-twisting mode is sort
of like wringing out a printed washcloth.
It's difficult to predict the results of
twisting; you're working with a hollow
outline of the brush, so vou can't see the
parts being overlapped and compressed.
This option's usefulness seems limited.

The surface-mapping feature, "Wrap-
on. . . ", spreads a brush onto a three-di-
mensional shape. When you choose ibis
option from the Brush menu, a sub-
menu appears listing the available
shapes. Select one. and the current brush
is replaced with an outline of the shape,
which you can reduce in size. As the pro-
gram calculates the new brush, the title
bar displays a count-down or raster lines-
to-go. This considerate convenience (it
appears elsewhere in the program as
well) lets you know whether you have
time to run lo the fridge before the cal-
culation is complete. Usually in a minute
or less, the brush reappears with the im-
age wrapped convincingly around the se-
lected shape.

The shapes submenu consists of Tube,
Cone, Ball, Ellipse. Free. Cube % , and
Cube *3. Free allows you to draw the
right side of a shape, which the program
mirrors to produce a symmetrical form.
The two cube selections allow you to
choose the orientation of a cube and
then, respectively, wrap the brush across
three sides, or stamp the complete image
on each surface, in proper perspective.

BASIC By The Numbers

"You got to move. You got to move. You got to move, child.

Sprites and BOBs

A UNIQUE FEATURE of Amiga Basic is its direct support for animation, making it easy to move objects around in a
window. It also provides a tool— the Object Editor— that you use to create objects you want to animate. No other
version of BASIC gives you so much in the way of animation tools.

You can manipulate two types of objects (known as graphics elements or GELs) from Amiga Basic — virtual sprites
and BOBs. In general, sprites are faster than BOBs. On the down side, sprites have a limited size and a limited
number ol colors. Although you should be aware of these limitations, you need not be too concerned with the
differences between BOBs and sprites: Amiga Basic handles both with the same commands.

In the drawer labeled BasicDemos on your Extras disk you will find a program called ObjEdit. This program lets
you easily create BOBs and sprites. It also saves the BOBs and sprites in a form that is understandable by the
Amiga Basic animation commands. Use of the Object Editor is explained on page 7-7 of the Amiga Basic manual.
For demonstration purposes I'll use the Ball that Commodore provides on the Extras disk.

First Steps

THE OBJECT EDITOR saves BOBs and sprites to disk files. Ball
is just such a file. To use any BOB or sprite, including Ball, you
have to load it into memory. Here's how you do it.

OPEN I, HI. "BasicOemos/Ball"
OBJECT.SHAPE 1, !NPUT$(LOF(1),1)

The first line opens the file Ball, indicates thai the program
will read from the file, and designates Ball as file #]. The sec-
ond line reads the description of Ball contained in the (lie and
designates it as shape #l. The INPUTS siaicmeni reads a string
that is as long (LOF = length of file) as file #l from file #1. Be-
cause this siring is already in a form BASIC can use, that's all
you have to do to define an object.

With an object safely defined in memory, you are ready to
move it around. You accomplish this by using the many object
commands available in Amiga Basic. The simplest command po-
sitions an object in the current window.

OBJECT.X 1,50
OBJECT.Y 1,50

These two lines position the upper-left corner of the object at

location 50,50 of the output window. To make the object visible,
you use the following:

OBJECT.ON 1

You're now just about ready to move the ball. First, however,
you designate the direction and speed you want to move.

OBJECT. VX 1,50
OBJECT. VY 1,20

The first statement above indicaies that you want lo move ob-
ject #1 at 5(1 pixels per second from left lo right. T he second
statement tells Amiga Basic to move the object 20 pixels per
second from top to bottom of the window. The result is that the
object will move in a diagonal path from upper-left to lower-
right.

You are now ready to move the ball. But first, lets throw in
some background with:

LINE (10,70) -(600,90)„BF

Now, lo get the ball rolling, enter:
OBJECT.START 1

And. to keep the ball within the output window, a lest:

WHILE OBJECT.X{1) < 600 AND OBJECT.Y(1) < 160
WEND

Once the object gels beyond 600 in the x direction or lfiO in
the y direction, the WHILE. , .WEND loop ends. The program
then cleans up and ends,

OBJECT.CLOSE 1
END

That's it. Your first animation program. ►

Watch Out For That Tree:

THAT AIN'T REALLY It, Of course.
Keeping an object in the window by
checking Its x and y coordinates is
slow and cumbersome. The best
way to keep track of an object is
with collision detection.

Amiga Basic keeps track of when
an object collides with another ob-
ject or with the border of a window.
By handling these collision events,
you can determine what happens
when an object threatens to stray
beyond the confines of the output
window. Here's a program that in-
corporates collision detection into
the listing from #46.

OPEN I, #1, "BasicDemos/Ball"

OBJECT.VX 1, -QBJECT.VX(I)

count = count + 1

IF count = 10 THEN z = 1

RETURN
END IF
z = 1
RETURN

The first changes In this program
from the one in #46 are the ON
COLLISION GOSUB statement and
the COLLISION ON statement. ON
COLLISION GOSUB identifies your
collision-handling routine — the rou-
tine that does what you want done
when a collision occurs. COLLISION
ON tells Amiga Basic to start re-
sponding to collisions. You should
issue both of these statements be-
fore you start moving an object.

The next four statements are the
main loop In the program. While z
is equal to zero, the program starts
Object 1 In motion and then goes
to sleep while Object 1 goes on its
merry way (as defined by your posi-
tion and velocity statements). The
program's "sleep" is interrupted
only when an event occurs that the
program is interested in.

When a collision occurs, Amiga
Basic puts information about the
collision into a queue. You use the
COLLISION) ) function to find out
the window where the collision oc-
curred, the object involved, and
what the object collided with.

When this program jumps to coll-
handler, it accesses the COLLI-
SION! ) function using -1 as an
argument. This argument causes
COLLISION( ) to return the number
of Ihe window where the collision
occured. Since this program uses
only the standard Output window,
this function call is unnecessary. I

included it In case you want to ex-
pand the program. I test to see that
the collision did occur in Window 1.
If it didn't, I assign a value of one
to variable z. This will terminate the
WHILE. . .WEND loop when the RE-
TURN statement is executed.

The next call to the COLLISION( )
function uses as the argument.
COLLISION(O) returns the object
number of the object involved in
the collision. Since I have defined
only one object in this program this
call is also unnecessary. You will
need it, however, in programs that
use more than one object.

The COLLISION(O) (unction re-
turns the number of the object to a
variable I labeled obj. The program
then tests to see if obj is equal to
one. If the object is not Object 1, z
is set to one and the program re-
turns to the WHILE. . .WEND loop.

Now you make one more call to
the COLLISION) ) function. This
time, you use the number of the
object as the argument. The func-
tion returns the number of the sec-
ond object involved in the collision
or a number that indicates which
window border was involved in the
collision. The following chart indi-
cates the values that correspond to
the four borders:

Border

Val

Top

-1

Left

2

Bottom

3

Right

4

In the example program, this last
call to COLLISION^ ) will always re-
turn a value to variable ctype that
corresponds to a window border.

I use a couple of IF. . .THEN
statements to test ctype. The first
checks to see if the collision was
with the top or bottom of the win-
dow. If this test Is true, I reverse

the y-velocity of the object and re-
turn to the WHILE. . .WEND routine.
If the first test is false, I test to see
if the collision was with the right or
left border. If true, I reverse the x-
velocity of Object 1. I then incre-
ment a counter and test to see if
ten collisions have occurred with
the right and left borders. 11 ten col-
lisions have occurred, I set z to one
and RETURN. This causes the pro-
gram to end after ten left and right
collisions.

The last part of the collision-han-
dling routine ends the program if
none of the above tests are true.

Note the way the program re-
verses the direction of both the x
and y velocities. It uses the OB-
JECT.VX and OBJECT.VY state-
ments in both their forms. For
instance, the statement

OBJECT.VX 1, -OBJECT.VX(I)

says "assign Object 1 an x velocity
equal to the inverse of the current
x-velocity of Object 1." OBJECT.VX
1, x is a command that assigns a
velocity x to Object 1. OB-
JECT.VX(1) is a function that re-
turns the current velocity of Object
1. The negative sign changes the
direction.

When the program returns to the
WHILE. . .WEND loop before 10 left-
right collisions have occurred, it
goes through the loop again, exe-
cuting the OBJECT.START statement
before suspending operation with
the SLEEP statement again. This
OBJECT.START is necessary be-
cause Amiga Basic issues an auto-
matic OBJECT.STOP command to
any object involved in a collision.

Once 10 left-right collisions have
occurred, the program exits the
WHILE. . .WEND loop, turns Object
1 off, frees up the memory the ob-
ject occupied, and ends.

Workstation
Amiga

Powerful personal computers,
including the Amiga,
are reshaping the current
scientific/graphics workstation
concept. Here we'll discover
if the Amiga, with a little
tooling up, will join the vanguard

of this movement,

ready to carry the heavy payioads
that will be required

of workstations of the future.

By Sheldon Leemon

Up until just a few years ago, the idea of computer workstations
brought to mind immediately a system of dedicated terminals
connected to a large mainframe host. And people working in the
fields of science, engineering, professional graphics, education.
and so forth would look to companies such as Apollo and Sun
Microsystems for (he answers to their high-powered computing needs. Now,
however, these same people are turning to more powerful desktop systems that
can handle demanding tasks, hut offer much greater versatility al significantly
lower costs. Apple's Macintosh II, IBM's PS/2 Model 80. and — yes — the Amiga
are some of the more popular choices.

With its powerful graphics and multitasking capabilities, the standard Amiga
models are already well-suited to many of the demands of a workstation. But
what else would you need in order to modify an Amiga so that it could meet
all the requirements of a true workstation?

We'll look at three basic areas — dynamic raw computing power, high-resolution
display, and networking capability — by which workstations are distinguished
from more ordinary computer systems to learn how yon can enhance the Amiga
to meet those requirements. In doing so, we should get a much more clear
picture of how the Amiga slacks up against other workstation solutions.

Accelerators and Coprocessors

The first requirement for a workstation computer is a lot of raw computing
power. Current standards demand a 32-bit microprocessor running at a double-
digit clock speed and a floating-point math coprocessor chip. Although lite
68(100 microprocessor used by the Amiga is powerful for a home computer, ii
is still two generations removed from the ti8030 — the most powerful member
of the Motorola family — and it tloes not have provisions for directly interfacing
to a 68881 or 68882 math coprocessor. Therefore, for compute-intensive appli-
cations, it is desirable to upgrade the Amiga to run a 68020 or 68030 processor.
Changing a computer's microprocessor usually requires both hardware
and software modifications. Fortunately, the Amiga operating system was
designed from the beginning with an eye towards upward compatibility
with more powerful Motorola processors. This means that almost all Amiga
programs run on machines equipped with a 68010, 68020 or 68030 processor
without change. The hardware considerations present a thornier problem.
Because neither the 68020 nor the 68030 is plug-compatible with the (58000,
you cannot simply drop the new processor into the existing socket — meaning
that you will need an interface board. Finally Technologies' Hurricane is a
piggyback board that drops into the 68000 socket, and it will run on two
Amiga models, (See the accompanying sidebar "Like a Hurricane" for am

evaluation of this board.) CSA also lias a piggyback
board for the A500 and A100U (although the company
is about to release a new, less expensive series — the
ND-500 and ND-1000 — which will accelerate standard
68000s so that they run at 14 MHz). The A2000 also
contains a CPU slot for a coprocessor board, and it
is in this slot that you would plug CSA's 68020 CPU
board or, if it becomes available in the US, Com-
modore's recently announced A2620 board. This
CPU slot makes it possible to override the 68000 chip

without physically removing it. (For a discussion of
CSA's accelerator board — and of the CSA 32-bit mem-
ory boards mentioned below — see "Turbocharging
Your Amiga 2000," p. 26, in the February '88 issue
of Amiga World.)

The speed advantage offered by the 68020 and
68030 chips result largely from the higher clock
speeds and full 32-bit data path they can use. Inte-
grating these chips into the existing Amiga system.
however, dissipates some of the benefits. Because the

Like a Hurricane

THE HURRICANE BOARD from Finally Technologies Is designed to make your Amiga computer run faster and smarter. The board
contains a 68020 microprocessor, a GB8S1 math coprocessor, and custom circuitry that lets these chips Integrate with your Amiga
computer. Finally has versions of the board available for two Amiga models. For purposes ot review, I tested the Amiga 1000
model in an A1000 and, with the help ot an adapter board, in an A2000.

The 68020 is the big brother of the Amiga's 68000 microprocessor. With minor exceptions, the 68020 will run software written
(or the 68000. The advantage to using the 68020 over the 68000 is two-fold. First, the 68020 is a full 32-bit processor— it fetches,
manipulates, and stores data in 32-blt chunks as opposed to the 16-blt chunks the 68000 stores and fetches. Also, the 68020
typically runs at a much higher clock speed than the 68000. In the case of the Hurricane Board, the 68020 runs at over 14MHz—
double the clock speed of the 68000. All else being equal— and It isn't— the 68020 should run a minimum of twice as fast as the
68000.

The 68881 is a cousin to the 68020. Its job is to perform mathematical calculations at blinding speeds. It is very good at this.
Hundred-fold Increases in mathematical computing power are not unusual when you use the 68881 instead of performing floating-
point math functions in software alone. Up to now, a major stumbling block to the acceptance of the 68881 has been the fact
that so little commercial software has been written to take advantage of the chip. With the advent of Workbench 1.3, which
contains automatic support for the 68881, more programs— and consequently more users— will be able to take advantage of the
power of the 68681.

Installation

The Hurricane board is a piggyback board. Rather than plugging Into an expansion slot (or the CPU slot on the Amiga 2000), the
Hurricane board plugs directly into the motherboard of your computer. More precisely, the Hurricane board plugs into the socket
that normally contains your 68000 microprocessor. Installation consists of opening up your Amiga, removing the 68000, and
plugging the Hurricane Into the vacated 68000 slot. Taking an Amiga 1000 apart is not too bad as long as you remember where
all the screws go.

The Hurricane is a tight fit in the A1000, so you have to be careful not to bend any of the long pins that plug the board into
the 68000 socket. I installed the board into two different A1000s as well as into an A2000 using an adapter board, t had no
problems with any of the machines once the board was Installed, but all the pulling and plugging weakened one of the pins on
the board. When I shipped the board to an associate to look at, the pin broke off in transit. The broken pin is not the result of
poor design or workmanship; It is a reminder that you (and I) should take extreme care in handling electronic components.

Compatibility and Performance

Because Commodore has constantly stressed the Importance of 68020 compatibility with software developers, I wasn't surprised
to find that none of the major commercial software packages I ran on the Hurricane board failed to function properly. What was
a bit surprising, and pleasantly so, was the fact that the Hurricane board worked properly with all my expansion hardware, including
a C Ltd Hard Drive an my A1000 and a BridgeBoard and A2090 Hard Drive Controller on my A2000. As far as compatibility is
concerned, moving from the 68000 to the Hurricane Board is a near-seamless transition.

Performance Is another matter. As the 68020 on the Hurricane Board runs at double the clock speed of the 68000, you might
expect to see at least double the performance in an Amiga with the Hurricane installed. Unfortunately, because of the architecture
of the Amiga, this theoretical increase in performance doesn't pan out.

In Its native configuration, the Amiga bus has a clock speed of 7.16MHz. This clock speed governs the 68000, the custom
chips, and access to chip RAM and ROM. Although the Hurricane board uses a 14.3MHz 68020, this chip must throttle back to
7.16MHz whenever it accesses anything on the Amiga bus. Consequently, as most Amiga functions involve accessing the bus,
the 68020 spends much of its time running at 7.16MHz. The result Is that you won't see a great increase in performance with
software running on the Hurricane board.

When I ran the Dhrystone benchmark program dryr (Dhrystones using register variables) from Fred Fish disk #1, I came up
with a figure of 645 Dhrystones with the Hurricane installed. This represents a 36% increase over the 472 Dhrystones you get

30 August 19SS

from a standard Amiga. When I tested the Hurricane board with software that supports the 68020/68881 combination, I got a more
pleasant surprise. A rendering with Sculpt 3D that took 999 seconds with a standard Amiga (arid 256 seconds with a CSA 68020
Board), was completed in 158.5 seconds on the Hurricane Board.

As you can see, the Hurricane Board provides a modest performance boost to any software your run. It comes into Its own,
however, when you run software that can take advantage of the on-board 68881. Math-intensive applications written for the 68881
will see performance increases of an order of magnitude over similar applications running on a native Amiga. Although Sculpt-
Anlmate 3D and Turbo Silver are the only packages that, as of this writing, use the power of the 68881, I expect many more
programs will do so in the near future. The Hurricane Board is ideal for heavy-duty graphics and number crunching; Its usefulness
will grow exponentially as the use of the 1.3 IEEE libraries becomes more widespread.

As this review was going to press, Finally Technologies forwarded a prototype 32-blt memory board for evaluation. This board
connects to the Hurricane board and provides native 32-bit memory for use by the 68020. When accessing this memory, the 68020
can run at full speed. With 32-bit memory, I got an all-time high of 1215 Dhrystones. Sculpt 3D rendering time decreased to 106.5
seconds. As you can see, 32-blt memory really makes the Hurricane sing.

Conclusion

Currently, the Hurricane Board is the best way to Increase the performance of your Amiga. Although it works best when you use
software that supports the 68881, It does increase the performance of your Amiga in general. With 32-blt memory, the performance
increase is substantial. The Hurricane Board is excellent for graphics and video applications. For general-purpose applications,
however, the promise of the Hurricane Board lies in the future, with the acceptance and widespread use the the IEEE libraries in
commercial programs.

existing RAM and ROM on the Amiga use a 16-bit
data path, these chips are limited to the narrower
path when they read instructions from normal Amiga
memory, or when thev execute ROM Kernel routines.
The highspeed processors must also pause periodi-
cally when communicating with the slower Amiga
memory. One way of counteracting these effects is
to connect the replacement processor to its own sup-
ply of 32-bil memory. This allows it to load programs
into the faster memory, and reduces the number of
times that processor must access the slower Amiga
memory when executing a program. Both Finally
Technologies and CSA offer 32-bit memory boards.

With the addition of a Memory Management Unit
(MMU), a coprocessor can transfer the Amiga ROM
Kernel routines into 32bil memory, and thus speed
up all operations that use the operating system. (An
MMU is a chip that protects memory from being
overwritten and remaps memory locations. Both
functions are used in moving the ROM Kernel rou-
tines to 32-bit memory. After the routines are copied
into 32-bit RAM, the MMU protects the memory from
being overwritten and reassigns the addresses for the
routines to the 32-bit RAM. A MMU is standard on
Commodore's A2620 board and is available as an
option on the oilier two 68020 boards.)

The kind of speed advantage that accelerators pro-
vide, therefore, depends on whether or not they are
equipped with 32-bit memory and an MMU. A plain
68020 board may not run programs significantly
faster than the normal 68000 processor, because it
must access the slower bus so often. With 32-bit mem-
ory, programs will generally run two to four times
faster. Y'et, without an MMU. even this speedup mav
not be very noticeable. A microprocessor often
spends most of its time waiting for input from the
user, and a 68020 chip really doesn't "wait" any faster

than a 68000. Also, much of a program's time is spent
calling ROM Kernel routines, which means slowing
down to Amiga memory speeds. Therefore, using an
MMU to transfer ROM routines to 32-bit memory
should result in noticeable speedups in such routine
operations as window redraws.

Perhaps even more important than the processor-
speed increases that accelerator cards offer is the way
in which they enable the integration of floating-point
math coprocessor chips (such as those provided by
CSA, Finally Technologies, and Commodore) into
the system. Both the 68000 and 68020 can perform
only basic math functions, while most floating-point
math is done by software. A 68881 math coprocessor
performs floating-point math in hardware — at speeds
far faster than software. You could connect a 68881
math coprocessor to a 68000 system by interfacing
it as a peripheral device (see MicroBotics) and achieve
up to 10 to 20 times faster math calculations than
software-based floating-point operations. When in-
terfaced to a 68020 processor, however, a 68881 will
do such calculations at speeds from 50 to 100 times
faster. (CSA tells us that, in addition to the 68881
math coprocessor it has been marketing, it is now
offering a 68882, which should produce even faster
calculation speeds.)

I lie problem with using ,i inalli coprocessoi i-> lli.u
in order to take advantage of it, software must either
be written specifically for the 68881, or must be
written using the Amiga IEEE math libraries. Because
the use of 68881 chips is still so rare, very few pro-
grams take them into consideration. Compilers such
as the AC Fortran ancl Manx C make special provi-
sions for generating 68881 code — meaning that for
custotn scientific applications, an Amiga can run
faster than a VAX 11/780. Although very few com-
mercially available applications programs take ad- »

AmigaWorld 31

vantage of the 68881, this may change as the use of
accelerator cards and math coprocessors becomes
more widespread and prices continue to fall. One
particularly well known example of such a popular
commercial software package making use of 68881
technology is a special version of Byte by Byte's
Sculpt-Animate 3D that can generate ray-traced draw-
ings up to 20 times faster when used with a 68020-
68881 accelerator. A similar type of package, Prism's
Turbo Silver, also shows dramatic increases in speed
when used with a 68881.

The Power Players

[Note: See the Product Information box for further infor-
mation about products described beknu.] Hardware accel-
erator boards for the Amiga are currently available
from CSA and Finally Technologies. CSA offers a
14MHz 68020 board with a 68881 math coprocessor,
along with two versions of 32-bit memory cards. One

type of memory card uses up to 2MB of static RAM
chips, which are much faster than dynamic RAMs,
but much more expensive as well. The other type of
memory card uses the slower dynamic RAMs, but
allows you to add up to 32MB of 32-bit memory. CSA
also offers a piggyback 68030 board (running at 16
MHz with a 68882 coprocessor) that offers processing
that is up to four times faster than the 68020.

The Hurricane board from Finally Technologies
offers a MMHz 68020. a 16MHz 68881, and up to
-1MB of 32-bit dynamic RAM. Finally also offers a
68030 upgrade that will boost your existing 68020
Hurricane board.

It is also possible to obtain 68881 math coproces-
sors separately. MicroBotics offers a multifunction
module for its StarBoard memory card that can add
a 68881 to any Amiga. Progressive Peripherals &
Software is also planning to offer memory products
that will incorporate the 68881, using the same

Amigas in the Laboratory

COMMODORE MAY HAVE a tough time selling the Amiga in certain markets, particularly the business community, where its name
is too closely tied to the home computer market. One market that doesn't have to be sold on the benefits of the Amiga, however,
Is the technical market. Reseaeh labs, universities, video production houses, even employees of other computer manufacturers
are not put off by Commodore's past; they recognize an elegant, sophisticated system when they see one.

Consequently, the Amiga is being used in ways that would shock anyone who looks upon it is a home computer. From the
banks of the Charles to the shores of the Pacific, the Amiga is satisfying the needs of technical users across the country.
■ At Ohio State University, Professor Charles Csuri of the Advanced Computing Center for the Arts and Design is integrating the
Amiga into the apE (Animation Production Environment) project. apE Is both a set of tools and a development environment that allow
researchers, students, and others to visualize the results of experiments and simulations. Currently, apE Is being developed on a
Cray supercomputer. One of the goals of the project, however, Is to make the power of the system available to students at all levels.
With its low cost and high performance, the Amiga is an obvious choice as a low-end apE workstation. Using Amiga products such
as Animate 30, the apE project hopes to make the concept of scientific visualization available to students of all ages.

• The University of North Dakota's Center for Aerospace Sciences has been studying the physics of clouds since 1980. One part
of the study is the Aircraft Icing Research Program, designed to determine those cloud structures more likely to produce Icing
on aircraft. The goal of the program Is to be able to predict and avoid icing situations. The Center uses an Amiga mounted In a
Citation jet as a front-end to a powerful minicomputer. The Amiga acts as an intelligent display station for the minicomputer. The
information it displays directs the pilot into different parts of a cloud, where critical data is gathered. Without the Amiga's real-
time display, flying into the correct spot in a cloud would be a hit-or-miss operation.

• At the University of Lowell (MA), Rich Miner of the Center for Productivity Enhancement directs a team of engineers and students
that Is looking to create a standard, device-Independent Image-processing system. Called the Image Kernal System (IKS), this
system lets researchers run the same Image-processing programs on different hardware systems. To demonstrate the system, the
Center has produced an expansion board for the Amiga 2000 that implements IKS. Future work at the center includes work on
pattern- and edge-detection and the development of high-resolution graphics hardware for the Amiga. (For more information on
the latter item, see the main article under the section "High-Resolution Displays.")

• At Palomar Observatory, Fred Harris of Cal Tech uses the Amiga to calibrate the Charged-Coupled Device cameras that have
replaced photographic plates as the mainstay astronomical-recording media. The Amiga is also used as a front-end data system
for observation and analysis at Palomar. In the future, the tracking system for the giant 5-meter Hale Telescope may be controlled
by an Amiga. (For more information, see "Searching the Heavens," p. 71, in the November 87 issue of AmigaWorld.)

• At the UCLA School of Medicine, Dr. Ron Harper uses the Amiga to combine information from different imaging technologies
to obtain a comprehensive view of the human brain. (See "Surgery 68000-Style," p. 57, In the January '88 issue of AmigaWorld,
for more Information.) Also at UCLA, Professor John Hodgson uses the Amiga to research how the body moves.

These institutions and others, such as NASA and Sandia Labs, have discovered the power and versatility of the Amiga. As
more people discover the price/performance advantage of the Amiga, you can expect to see it on many more scientific
workbenches. D

Enter the Integrators

ONE PROBLEM FACING the Amiga In the workstation market Is the tact that every installation must come up with its own hardware
and software configuration. Faced with continuously "reinventing the wheel," many customers opt for more mature systems. Such
a situation Is ripe for companies willing to do the system configuration.

Tucked away in a basement office in Ludlow, Massachusetts, is a small company with big plans. Amicore International is a
start-up operation that hopes to capitalize on the power of the Amiga 2000 to revolutionize the workstation market.

The goal of Amicore Is to develop a "hypermedia" workstation using the Amiga as the foundation. By combining graphics,
audio, video, and other media as only the Amiga can, Amicore hopes to be able to produce a product that appeals to scientists
and vldeographers alike, and anyone in between.

Amicore consists of four principals with varying backgrounds. President Andy Petrie is an inventor with a long history in high-
tech companies, Rudi Vogel comes from a marketing background with DEC, Don Petrie Is a graphics designer, and Mike Pefreila
Is the video expert. They hope to provide the know-how needed to catapult the Amiga into the high-end workstation market.

Amicore Is starting small. To make ends meat, It produces adapter cables that let you run Amiga 1000 peripherals, such as
Dlgl-Vlew and FutureSound, on the Amiga 500 and 2000. By November, the principals expect to offer their first workstation system,
consisting of an Amiga 2000, advanced graphics hardware (that they plan to license), and commercial and custom software.
Amicore wants to hear from other Amiga developers Interested in the hypermedia concept. The address is Amicore International,
451 Center St., Ludlow, MA 01056.

To further develop the hypermedia workstation, Amicore is building a digital media lab. The lab will be a proving ground for
the hypermedia concept. In addition to selling bundled turnkey systems, Amicore expects to sell entire hypermedia installations,
and to provide training and service.

Does Amicore have a chance? Based upon the growing realization of the Amiga's capabilities in the video and scientific markets,
the future looks good. Its success will depend upon how well It integrates technologies and products from different sources. G

scheme as Microbotics to interface the chip. Official
support for the 68881 interfaced as a peripheral
device will be included in Workbench 1.3, which
should spur software manufacturers to add math chip
support to more of their software.

A number of other accelerators are currently in
the works. MicroBotics is working on a full line of
accelerators for A500 and A2000 computers. Com-
modore has already announced its own A2620 ac-
celerator card for the A2000 in Europe, containing
a 68020, a 68881 math coprocessor, a 68851 MMU,
and two or four megabytes of 32-bit RAM. Whether
the A2620 will be available in the US is subject to
speculation, as Commodore is sensitive about tread-
ing on the toes of the growing number of third-party
accelerator manufacturers already in the American
market.

High-Resolution Displays

The second characteristic of workstations is a very
high-resolution display screen. The Amiga's 640 x 400
16-color display capability isn't bad for starters, par-
ticularly as its ability to use the overscan area of the
screen can push this resolution to over 700x440. In
order to get 400 lines of resolution on a 200-line
monitor, however, the Amiga must use an interlaced
display. This type of display makes the Amiga a good
choice for video work, where interlacing is standard,
but the "flicker" it causes makes the computer's high-
resolution mode very difficult to work with for more
standard computer applications.

MicroWay offers a de-interlacing board called the

flickerFixer, which retails for $595 and fits into the
video slot of the Amiga 2000. Because the A500 and
A1000 both lack this video slot, they cannot take
advantage of the MicroWay card. flickerFixer pro-
vides a steady, non-interlaced 400-line output that
can be displayed on a multi-scanning monitor, such
as the NEC MultiSync. Although the combination of
display card and monitor is fairly expensive by Amiga
standards, the business or professional user may find
it to be well worth the cost. Using flickerFixer with
the A2000 is something of a revelation. It makes
programs such as Professional Page and X-CAD look
much more like worthv competitors to similar pro-
grams on IBM and Macintosh systems. It even makes
the Workbench look more professional. flickerFixer
should enhance almost any kind of professional ap-
plication, except those using video software, which
requires an interlaced output. In general, high-reso-
lution animated displays will always appear a little
jerky, because flickerFixer combines the interlaced
fields. (For a more complete evaluation of flicker-
Fixer, see p. 64 in this month's Review section.)

Commodore has announced that it too is working
on several display enhancements, including an en-
hanced chip set. Consisting of upgraded Agnus, Dcn-
ise, and Gary chips, the set will output a non-
interlaced 400-line display to dual-scanning or multi-
scanning monitors. The new chips will not be avail-
able until the release of Workbench 1.4 and probably
will not work on the Amiga 1000. They will, however,
be a cheaper alternative to the flickerFixer, although
it is doubtful they can provide all of its functionality. •

AmigaWorld 33

Because it would be difficult to increase the existing
display bandwidth, the 400-line non-interlaced dis-
plays will have only half as many color bit planes as
the 200-line displays. This means a maximum of four
colors in 640x400 mode, with the same sort of per-
formance penalities for memory operations in chip
RAM that you currently get with 16-color hi-resolu-
tion displays. Still, a true 640 x 400 color display gets
us a lot closer to workstation range.

Commodore is also working on a new high-reso-
lution gray-scale monitor, the A2024, which should
sell for under $1000. Ii will work with all Amiga
models because it uses the standard Amiga video port.
The A2024 can be used to de-interlace the norma!
Amiga display, providing a 640 x 400 display with up
to eight grav levels, and it will also support an ex-
tended display of up lo 1008x800 pixels at two or
four gray levels. Normally, the largest display segment
that the Amiga hardware can output at one time is
640 x 400 pixels, two color planes deep (four colors).
Therefore, a combination of hardware and software
trickery is required to create the extended display.
The software creates a bitmap made up of from four
to six normal-sized displays. It then sends this display-
out a piece at time lo the monitor, which stores each
piece in RAM until it can assemble the entire picture.
As a result, the screen is only redrawn 10 or 15 times
a second, instead of the normal 60 times.

This characteristic will make it difficult to do
smooth animation on the A2024, but it will not impair
its usefulness as a display for desktop publishing or
CAD programs. Because the screen memory used for
the extended display is organized as one large Amiga
bitmap, all graphics and text operations are carried
out using the normal Amiga operating system rou-
tines. Programs that can adapt to a larger-than-normal
size Workbench screen will run on the extended
A2024 screen without any changes. Other programs
will need only minor modifications to take advantage
of the big screen.

"VIEWING" THE FUTURE

Such enhancements take the current Amiga display-
hardware about as far as it can go. In order to get
closer to the kinds of screen resolutions typical of
workstation computers, entirely new display hard-
ware is needed. A group at the Center for Productivity
Enhancement at the University of Lowell in Massa-
chusetts has built a prototype of a graphics card for
the Amiga 2000 that can display 1024x800 pixels,
using 10 color bit planes. This means that 1024 colors
(out of a palette of 16.7 million) can be displayed on
screen at once. The board uses a Texas Instruments
TMS 34010 display chip clocked at 50MHz, and in-
cludes 512R of dynamic RAM foron-board programs
and 1.25 megabytes of video RAM. The display chip
contains its own on-board blitter. Although the group
is undecided about manufacturing the board com-
mercially, it points out that similar cards in the IBM
PC market cost about S2500. (For more information

about the Lowell group, see the accompanying side-
bar "Amigas in the Laboratory.")

While the Lowell card provides the type of high-
resolution color display typical of workstations, the
question of how to get software to use that display
remains up in the air. The Lowell group plans to
provide a graphics library that could be called directly
from software, and it is working on display programs
to allow several IFF files to be shown on the display
at the same time. It also would like to implement an
X-Windows driver, so that an Amiga with this en-
hanced display could be used as a high-resolution
graphics terminal for X-servers. The most desirable
way to integrate this high-resolution display, however,
would be to develop Intuition support for it. Existing
Amiga software could then take advantage of it with-
out substantial modifications. To develop such sup-
port would require a complete rewrite of the current
Amiga ROM Kernel graphics library-, which is linked
inextricably to the current Amiga display hardware
and blitter. As formidable as such an undertaking
may seem, it is absolutely necessary if display reso-
lutions on the Amiga arc to catch up with the current
state of the art.

Networking

The final requirement for workstations is the ability
to connect with mainframe computers and other
workstations over a network. In a group development
situation, it is vital that all members of the group
have access to a collection of shared files. Networking
also makes it possible to use the Amiga as a graphics
display engine for data generated by a number-
crunching mainframe computer.

The only full-featured network system for the
Amiga is the Internet package from Ameristar. At
S899, it includes an Ethernet controller board and a
number of programs for communicating over the
network. The most powerful software it provides is
an implementation of the Network File System (NFS)
widely used on Unix systems in universities, research
labs, and large corporations. Using NFS, the Amiga
can transparently access files stored on a Sun or VAX
system. For example, what the VAX system sees as the
uscr/amiga directory, the Amiga may see as DH0:.
Other programs allow the Amiga to run as a terminal
on the network, and to execute programs on a host
computer. There is also software for retrieving Hies
from non-Unix systems.

Ameristar representatives say that the company
sells about one-half of its controllers to universities,
who want to use the Amiga to add graphics output
to mainframe applications, and another half to cor-
porations, who want to use Amigas largely as inex-
pensive terminals on existing Ethernet systems.
Ameristar plans to add support for networked win-
dowing systems, such as X-Windows and Sun Micro-
systems' NEWS. Support for such systems would make
it possible to run mainframe programs using a win-
dowing graphics interface on the Amiga, and X-Win- 1

dows, which would further enhance the machine's
capabilities as a graphics terminal. Ameristar also
hopes to introduce a lower cost Ethernet network
card for the Amiga 500.

The only other network currently offered on the
Amiga is a low-cost point-to-point system based on
the C Ltd SCSI controller. The controller, which
ranges in cost from S299 for the 1000 version to $199
for the 2000 version, is normally used to interface
SCSI hard drives. Using the SCSI-Net software the
company packages with the controller, however, it is
possible for several Amigas to share a single hard
drive over the SCSI bus, at SCSI speeds. While this
setup is useful in certain situations, it is subject to a
number of limitations. There is a 30-foot maximum
on cable lengths between machines, and only eight
devices can be connected to the bus at any one time.
There are also no provisions for file-locking, a feature
that prevents one user from overwriting changes
made to a file by another user. The company plans
to remedy these deficiencies in the next version
(3.0)— due out shortly after the official release of the
1 .3 version of the Amiga operating system— by adding
file-locking, by implementing noding (which will al-
low the interconnection of up to 255 buses), and by
adding other enhancements that should make SCSI-
Xct a much more LAN-like system.
Although not yet available, some other networking

systems are rumored to be in the works. Commodore
is reported to be interested in developing a TOPS
network system for the Amiga, which would enable
communication with Sun, Macintosh, and DEC com-
puters. The plan calls for a system based on low-cost
hardware similar to that of the Macintosh Apple Talk
network. As of yet, however, no definite plans for
such a system have been announced.

Even without the additions described in each of
the three sections above, the Amiga stacks up pretty
well as a personal workstation. The availability of
third-party network systems, display enhancements.
and accelerator boards do, of course, make the ma-
chine very attractive to the scientific, educational,
and technical communities. This does not mean, how-
ever, that Commodore can simply let the third-party
developers blaze the workstation trail all alone. Work-
stations are growing ever more sophisticated and less
expensive. Commodore must act quickly to prepare
the Amiga for the higher-resolution displavs, 32-bit
buses, and built-in networking capabilities that are
increasingly becoming standard features on personal
computers. ■

The AmigaDOS

Through a strict regimen to slim down and strengthen up, ARP will

have your CLI commands benchpressing more directories and running more files

than their overweight AmigaDOS counterparts thought possible.

By W. Jeffrey Blume

UNDER THE SUPERVISION of their ARP (Amiga-
DOS Replacement Project) trainers, the CLI com-
mands are trimming down and toning up. Originally
programmed on a diet of the cumbersome BCPL
language (Basic Combined Programming Language,
a predecessor of C), the AmigaDOS commands are
slow and large with limited power. ARP, a joint pro-
gramming effort led by Charlie Heath of Microsmiths,
is whipping the BCPL flab into 68000 assembly-lan-
guage muscle. The ARP programs, and arp. library
that they depend on, will replace the existing C di-
rectory commands. Completely backward compatible
with AmigaDOS commands, the ARP commands of-
fer you many new features, including greater wildcard
capabilities, more on-line help, resident commands,
environment variables, resource tracking, and low-
memory management. Needing an average of one-
half the calories of the current AmigaDOS com-
mands, the ARP replacement programs melt away
approximately 35K from your Workbench disk, while
supplying more power, speed, and accessibility.

Load, Set, Run

The most apparent ARP improvements are the new
commands that have no BCPL equivalents — ARUN,
LOADLIB, and SET. Two other commands are new

to users of AmigaDOS 1.2, but familiar to 1.3 own-
ers— ARP's ASK and RESIDENT. When included in
script files, ASK lets you query the user about per-
forming specific tasks. RESIDENT lets you make com-
mands resident in memory, allowing much faster
execution than even RAM-disk-based commands.

ARUN combines the capabilities of RUN with those
of Heath's public-domain program, RUNBACK. As
with AmigaDOS' RUN, ARUN will execute a program
in the background and return CLI control to you.
ARUN's additional arguments let you set the stack
for the program and its task priority. With many
programs, you can even close the CLI while the back-
ground program is still running, which frees about
20K of memory. One minor drawback is that you
must use escape characters to pass strings through
ARUN. The * is ARP's default escape character; if
you prefer to use a different character, the new SET
command lets you reassign the default.

LOADLIB will load any disk-based library. If your
boot disk is too full to include all the libraries you
need, you could load them into the system with LOAD-
LIB. With SET vou can assign values to environment
variables, which let you configure different aspects
of the Amiga's system environment. Similar to the
SET provided with Manx Aztec C, ARP SET is com- i

patible with programs compiled by Manx that read
environment variables.

ARP currently supports several environment vari-
ables — copyflags, date-format, and listarchive.
Through SET and the copyflags variable you can
instruct the COPY command to reproduce certain
characteristics of the original file when it creates the
new file. You can duplicate the filenote and the orig-

inal date, as well as the Read, Write, Execute, Delete,
and Archive flags. If you would rather avoid the SET
command, you can instruct COPY to duplicate the
file characteristics by supplying the FLAGS keyword
and its options in the COPY command line. Either
method is an improvment over the BCPL COPY,
which cannot duplicate filenotes and stamps the cur-
rent system date on the new file.

arguments now does, increasing the CLI's power
enormously. For example, with the new RENAME
command you can type:

RENAME ARP_c/* to c

to move all the commands from a directory named
ARP_c to the logical device C. With the BCPL RE-
NAME command you could rename only one file or
directory at a time.

In addition to accepting the wildcard, several ARP
commands can handle multiple sets of arguments. In
a single ARP ASSIGN statement, for example, you
can transfer all of the system logical devices to a hard
drive. With AmigaDOS, you would have to call AS-
SIGN for each individual device — a minimum of
seven separate calls. The new ADDBUFFERS lets you
assign buffers to four different drives in one state-
ment, while MAKEDIR, RESIDENT, and TYPE also
accept multiple arguments.

For help remembering all the new ARP commands
and options, type a command followed by a question
mark. As with the original commands, the system will
respond with the command template. Typing a ques-
tion mark after the template will give you a second
line of clarification.

No More Crutch Conventions

Not as obvious to users, the current operating system
presents handicapped power to developers. Con-
strained by its DOS library and arcane BCPL lan-
guage conventions (see the sidebar "Programming
With a Forked Tongue"), programmers are forced to
maintain two sets of conventions, one that BCPL
understands and one for the rest of the system. With
the consistent arp. library, programmers can organize
their code, creating more efficient programs. Several
of the library's routines help developers speed up
and streamline the dialog between their programs
and the users. Programmers can create and include
environment variables in their commercial software
for setting mulitple defaults. The arp. library's
FileRct|ucst( ) function is a greatly enhanced version
of the Heath file requester, reputed to be one of the
fastest on the Amiga. Most requesters read and display
an entire directory before letting you take any action.
The Heath requester (used by many Aegis programs,
Photon Paint from Microlllusions, and City Desk
from MicroScarch) allows you to click on a file or
directory as soon as it is displayed. The requester
immediately interrupts its current directory read, and
either loads the file or displays the new directory list
you specified. You will especially appreciate this
shortcut when you access deeply nested directories.
The ARP requester improves further on its prede-
cessor by adding a parent gadget, which will send
vou back one level in the directory hierarchy, and
also by allowing programmers to easily append mul-
tiple gadgets, such as DFO:, DHO:, and DHL. Devel-
opers can also add string gadgets to supply filters for
selectively displaying files. For instance, you could

include a filter so that a paint program's requester
would display only files with the suffix .pic. When
the user asks for a DIR listing, the requester will not
clutter the Using window with extraneous files. To
accelerate directory accesses even more, click in the
listing window with the right mouse button. The re-
quester will display a listing of all available physical
and logical devices, allowing you immediate access
to files without having to wade through the interven-
ing levels of the directory tree.

While the developers were tinkering they added
numerous other useful functions. The GADS( ) ar-
gument parser helps provide a consistent format for
CLI commands. Assign( ) and ASyncRun( ) allow pro-
grams to make logical device assignments and run
external programs, without having to access the disk-
based ASSIGN and RUN commands.

One function needed by any multitasking operat-
ing system, but not supplied with AmigaDOS, is re-
source tracking. In a multitasking system, several
programs must be able to share the same resources,
such as memory, files, logical devices, and so on,
freeing up those resources when they are finished,
rather than doing such nasty things as overwriting
each others' data structures or exiting while leaving
200K of memory tied up.

Using functions supplied by the arp. library, you
can track and free resources automatically when you
close it. ARP's resource tracking also provides low-
memorv management, permitting memory reserved
by a program to be released in a low-memory situa-
tion, if the program is not actually using the memory
at that time.

Besides offering totally new commands, ARP adds
extra capabilities to AmigaDOS staples. You can use
CD and PROMPT together to display the current
directory, the task number, and a text string in the
CLI prompt. The new CHANGETASKPRI can change
the priority of a task that is already running. DELETE
now will accept an unlimited number of files as ar-
guments, and it also has an interactive ASK keyword
you can use with wildcard deletions. DIR offers op-
tions to display file size, to list files only, or to distin-
guish directories with inverse highlighting. ECHO no
longer needs its string arguments to be enclosed in
quotes. Through its new ability to accept multiple
arguments, MAKEDIR can create a directory, then
nest subsequent levels of directories within it, all with
one invocation of the command. For a command by
command list of ARP's improvements, sec the accom-
panying chart, "Comparision of ARP and AmigaDOS
Commands."

Programming With a Forked Tongue

SINCE ITS INCEPTION, AmigaDOS has been speaking out of both sides of Its mouth. The original Amiga programmers wrote
most of the Amiga ROM Kernel (housing the Intuition. library, dos.library, graphics. library, and so on, all managed by Exec) in
efficient 68000 assembly language or C. Meanwhile In England, Metacomco was programming the DOS (Disk Operating System,
which Is only a part of the greater OS) In BCPL (Basic Combined Programming Language, a predecessor to C).

The clash comes because the BCPL conventions are much different (some are even exactly opposite) from analogous
conventions in C and 68000 assembly language. Consequently, the DOS does not integrate well with the rest of the system.
The specific problems lie in the way BCPL addresses memory (BPTRs), how it handles strings (BSTRs). and the stack.

BPTRs will allow only longword alignment. To insure that memory addresses are longword aligned, BPTRs divide the
addresses by four, before acessing the dos.library. In C, the compiler handles address alignment: odd alignment cannot happen.
According to Charlie Heath, one of the principals of the ARP project, the BPTR problem arose from the particular implementation
of BCPL that Metacomco used, rather than from problems Inherent In the language.

BSTRs are constructed quite differently than C strings. The first byte of a BSTR gives the length of the string, then the string
itself follows with no terminating character. Because only one byte is used to define Its length, a BSTR is limited to 255 characters.
A C string can have an unlimited number of characters, marked at the end by a terminating character. Finally, a BCPL stack grows
upward from Its base in memory, exactly opposite to the way the 68000 processor manages the stack, moving downward from
the base. The BCPL stack Is decremental, while the 68000 stack Is incremental.

The language problem requires programmers to maintain two different sets of conventions — one for addressing the dos.library
and another for addressing the rest of the operating system— thus slowing development and Increasing code overhead. This
convoluted code was a significant motivation for the development of ARP. "The data Interfaces are all different. . .that was
half the problem, a nasty half," says Heath.

The other half of the problem, according to Heath, stems from the fact that the code in the dos.library and BCPL library Is
simply Inefficient. The BCPL library was undocumented and could not be used by any programs but the BCPL commands.
Programmers were forced Into maintaining a parallel set of functions, thus duplicating their efforts.

One of the ARP programmers' primary goals was to remove any dependency on the BCPL library by replacing all the BCPL
commands and supplying a library of functions that all programs could call. They succeeded In an eloquently compact fashion.

-WJB

uses a as an escape character. You can issue SET to
assign as the escape character, but the default is an *.
The COPY template in the manual erroneously des-
ignates FLAGS as a switch rather than a required key-
word; the on-line template shows FLAGS/K. If you
issue aCOPY command with all but the flags argument
correct, however, COPY displays its extended help
message, rather than the template, while neglecting to
mention the FLAGS keyword at all.

Integrating the commands into your system is quite
easy. The distribution disk's execute file will install
ARP automatically on your boot disk. If you are CLI
inclined, you can issue the following commands:

copy ARPvl.Llibs/arp.library to libs:
copy ARPvl.Lc to c:
loadlib libs:arp. library

ARP is freely distributable with certain restrictions,
and vou can download it from most on-line services
and bulletin boards that have Amiga special interest
groups. If vou prefer the old-fashioned postal service
to telecommunications, mail $5 per copy of ARP to
ARP Support, c/o Microsmiths Inc, PO Box 561, Cam-
bridge, MA 02140.

I found the ARP commands to be smaller, faster,
and more powerful than their BCPL forerunners.
Their compact size is especially helpful when vou are
running the commands out of a RAM disk. Be warned,
however, that all benefits come at a price. ARP version

1.1 does not currently support BI.XDDRIVFRS, DISK-
DOCTOR, ED, EDIT, ENDCLI, EXECUTE, FAULT
(ARP's WHY does double duty for WHY and FAULT),
LOADWB, NEWCLI, and RUN (see ARP's ARUN).
Wbrk is in progress, however, and the developers
should soon release new additions to ARP's command
set, including support of AmigaDOS 1.3's Fast File-
System.

Commercial programs are beginning to support
ARP. TxEd Plus from Microsmiths Inc. naturally sup-
ports the arp.library. Epyx's Sub Battle Simulator
sports the ARP file requestor. Redact (a desktop-
publishing program from Top Down Development)
and WShell (a CLI enhancement program from Wil-
liam S. Hawes) are alsojoining the ARP parade. Even
Commodore is taking notice. According to Heath,
the ARP programmers offered the current version
of ARP to Commodore free of charge, and would
like to see it in ROM. Apparently Commodore is
actively considering it, but because of negotiations,
could not comment publicly.

In a market where the need for instant gratification
pushes producls out the door before they are ready,
the careful planning and execution demonstrated by
its developers make ARP a welcome exception. ■

With its many new device drivers and handlers,

Workbench 1.3 will iet you add a lot more hardware and software

devices to your system than 1.2 did.

hen left to its old devices, the 1.2 operating sys-
tem's MOUNT command could handle simple pe-
ripheral operations adequately, but realized little of
the versatility of the Amiga's system for adding de-
vices. Used in conjunction with the Mountlist text
file found in the DEVS: directory, the MOUNT
command allows you to add almost any type of
hardware or software device to the system.

Mounlable device drivers let AmigaDOS interact
with external hardware devices such as a hard
drive. Devices may also consist merely of software
drivers that use existing system resources in a new
way, as with the RAM disk device. Mountlist de-
scribes various device attributes, and specifies the
file that contains the device driver or handler soft-
ware. Squandering potential power, the 1.2 release
contained Mountlist entries for adding only the
A 1020 5 '/< inch drive as an AmigaDOS device and
a hypothetical device called AUX: (similar to the
serial device).

With the release of Workbench 1.3, Commodore
has harnessed much more of the MOUNT com-
mand's power, letting you add many standard de-
vice types to your system. For faster data access,
Commodore added a recoverable RAM disk and
Fast File System. The new PIPES: device and AUX:
device let you talk to other commands and termi-

nals, while the SPEAK: device talks back to you. In
case you have trouble issuing the new commands,
Commodore added a command-line editor.

Totally RAD:

Perhaps the most interesting of the new devices is
RAD:, a second RAM device, which, like the famil-
iar RAM; device, uses part of the computer's work-
ing memory as an electronic disk drive. Rather
than replacing RAM:, RAD: complements it and
has many important differences. RAM: is an inte-
gral part of the AmigaDOS system; you create the
RAM: device merely by referring to it in an
AmigaDOS command. To access RAD:, on the
other hand, you must add it to the system with the
MOUNT command, and be sure the file containing
its device driver, ramdrive.device, is in the DEVS:
directory. R'\M: adjusts its size automatically, ac-
cording to its contents; as you add more files, it
grows. Unlike RAM:, whose size is limited only by
the amount of available memory, RAD: has a fixed
size you specify in the Mountlist entry you use to
mount it.

Because it is of a fixed size, RAD: acts more like
a floppy disk than a RAM disk. Like the standard
3 'A inch floppy, RAD: is set up as a double-sided
drive, with 512 bytes per sector, and 1 1 sectors per*

track. Each track (also called a cylinder) uses I IK
of memory (512 bytes per sector x 11 tracks per
sector x 2 sides). AmigaDOS determines the num-
ber of tracks used for RAD: by the LowCyl and
HighCyl entries in the Mountlist. An entry of
LowCyl = ; HighCyl = 21, for example, allocates 22
tracks, at 1 IK per track, for a total of 242K of
memory, enough to store all of the files in the
Workbench's C directory. If you have a couple of
megabytes of fast memory on your Amiga, you
could even set the HighCyl value to 79, for an
880K RAD: drive, the exact same size and layout as
a floppy disk. With the RAD: drive the same size as
a floppy, you can use DISKCOPY to copy an entire
floppy to RAD:, or vice versa. You can even format
the RAD: drive, which you can not do to RAM:.
The most important difference between RAD:
and RAM:, however, is RAD:'s durability. Because
both use the computer's memory to simulate disk
storage, when you turn off the computer, you will
lose the contents of both devices. A warm boot is
another story. While RAM: loses its contents when-
ever you press the CTRL-Amiga-Amiga key combi-
nation, or you encounter a Guru error, RAD:, a
recoverable RAM disk, protects its cargo. As long
as the error that caused the Guru Meditation did
not scramble the contents of memory, with the 1.2
Kickstart ROM you can mount RAD: again, and it
will reappear with its contents intact. Not only can
you recover the contents of the RAD: drive after
rebooting, but also, with Kickstart 1.3, you can
even reboot from the RAD: device. Along with the
ability to boot from such devices as hard disks and
network boards, the 1.3 ROM chip adds the ability
to reboot from RAD:, provided that it has been
mounted, and the operating system does not find a
bootable disk in drive dfO: at warm-start time. Even
if it uses a boot disk for a warm start, Kickstart 1.3
restores RAD: automatically upon warm boot, so
you need not remount it. Of course, if you have an
Amiga 500 or 2000, you will have to change Kick-
start ROM chips to gain this ability; if you own an
Amiga 1000, however, you need only insert the new
Kickstart disk.

Move It Along

Because RAD: is a mountable device that can be
formatted, it can also take advantage of the new
Fast File System (FFS). Commodore added this al-
ternate file-system handler to Workbench 1.3 to
make hard-disk access faster, but, in fact, you can
use it for any mountable disk device, except the
3 '/a inch floppy drives. Because the FFS stores data
differently on disk than the normal AmigaDOS file
system, 3 % -inch drives using the new system can-
not read current AmigaDOS disks. Non-removeable
media, however, such as hard disks and RAM disks,
do not face this problem.

To use the FFS on RAD:, you must add two items
to the RAD: entry in the DEVS:MOUNTLIST file.

Anywhere after RAD: and before the # that ends
the entry, insert:

GlobVec= -1

FilcSystem = ITasiFileSystem

In addition, you must make sure the FastFileSystem
file mentioned in the second line appears in the 1:
directory on your Workbench disk. After you have
changed the Mountlist entry, use the command
MOUNT RAD: to mount the drive. Because you are
using a different file system than the default, you
must format the drive before you use it, but using
the new QUICK option of the FORMAT command
shortens the process:

:SYSTEM/FORMAT drive RAD: name Speedy
QUICK

Although using the FFS on the recoverable RAM
disk speeds up operations somewhat, because it is a
RAM drive, RAD: responds fairly quickly without it.
The Fast File System saves time, but at a price. Un-
der Kickstart 1.3, you cannot reboot from the RAM
drive if you format it with the FFS. In fact, with the
1.3 ROM, you cannot even recover the contents of
the RAM drive when you reboot after formatting
with the FFS, because the drive is automatically
mounted on warm start as a normal DOS file-system
device. As Kickstart 1.3 is expecting the RAM drive
to be in the old AmigaDOS formal, it thinks that
RAD: is not a DOS disk. If you use Kickstart 1.2,
however, you have built-in protection because the
operating svstem requires you to mount the drive
again after a warm boot. Even though you cannot
reboot from the RAM drive, you can recover its con-
tents even if it is formatted with FFS.

AmigaDOS Pipes Up

The PIPE: device handler on Workbench 1.3 emu-
lates the pipes feature of MS-DOS that allows you
to transfer the output of one program to the input
of another. Let's say you want to display a large
disk directory on screen, but do not like using DIR
because it outputs file names in a continuous
stream and does not pause when (lie screen fills
up. By piping the output of DIR to the MORE pro-
gram, which displays text one screen at a time, you
get the information you want, in the format you
prefer. In UNIX or MS-DOS, you would issue a
command such as DIR | MORE. Because the Amiga
command shell does not recognize the | operator,
you must simulate pipes to achieve the same result.

As with Workbench 1.2. in 1.3 you can redirect
files to a temporary storage area on the RAM: disk.
To transfer DIR output to MORE, type:

DIR >ram:temp
MORE ram:temp

DELETE ram:temp

A more efficient method, especially for large
files, is to mount PIPE:, whose handler is found in ►

SPEAK

can read aloud

any file that

you can write

the file l:pipe-handler. The PIPE: device acts as a
conduit, directing the output of one program to
the input of another. One process writes to the
pipe, assigning il an arbitrary file name (such as
pipe:temp). Each pipe name uses a 4K buffer,
which means only that much may be written to the
pipe before the writing process is blocked. When
the second program reads the 4K buffer (by access-
ing the same File as was written to), the first pro-
gram can write 4K more of data, until all of the
output is transferred. Once you issue the command
MOUNT PIPE:, you could pipe the output of DIR
to MORE with the command sequence:

RUN DIR >pipe:temp
MORE pipe:temp

Note that you use RUN to spin off a separate pro-
cess for DIR. Both commands cannot use the same
CLI process because if the directory output is
larger than 4K, DIR will not terminate and give
back the CLI prompt until MORE has read all of
its output.

The roundabout method thai PIPE: uses to simu-
late pipes may not be as simple as that available on
other systems, but it does have some unique advan-
tages. In addition to the traditional pipe transfer
described above, you can use PIPE: for its buffer-
ing capabilities alone. Many terminal programs, for
example, download files in a synchronous fashion.
They receive a block of data, send it to the disk,
wail until the disk write is finished, and then ask to
receive the next block. Each intermediate disk
write slightly delavs the transmission. You can
avoid the delay by downloading to a file in RAM:.
but you run the risk of filling up the RAM disk
before the file transfer is completed, or of forget-
ting to copy the file to a floppy before turning off
your computer. A belter solution is to use the
command

COPY pipe:temp TO dfO:downfile

before running your terminal program, and then
downloading to the file pipc:temp. With this se-
quence vou can buffer large amounts of data be-
fore any writes take place, meaning fewer delays.
At the same time, you avoid the risks associated
with downloading to RAM:. When the download
process concludes, your file is stored safely on disk.

New AUX: and Squawks

If you need to transfer data to another terminal,
you will appreciate the new AUX: device, whose
handler is located in the file l:Aux-Handler. AUX:
transfers data through the serial port, much like
the SER: device; the difference is in the buffering.
While SER: buffers its output, sending it out only
after a 512-byte block has accumulated, AUX: pro-
vides unbuffered communication with the serial
port. With the unbuffered AUX:, you can create a
CLI window thai uses the serial port for its input

and output by mounting the AUX: device, and
typing:

NEWCLI AUX:

This procedure lets you hook up another com-
puter or terminal to your Amiga, and give
AmigaDOS commands from the second machine
over the serial port, or even over a modem. While
you cannot, of course, run Intuition-based window-
ing programs on your remote terminal, you can
use such CLI commands as DIR and INFO to gain
information about the Amiga disks. With the TYPE
command you can send files to the remote screen,
where they can be captured to a buffer file. While
serial-port CLI's do not exactly make the Amiga a
multiuser system, they do come prettv close to it.

To make the Amiga's built-in speech synthesis
more accessible, Commodore added the SPEAK:
device handler to the 1.3 Workbench. SPEAK: is
similar to the SAY program in the Utilities drawer,
in that il converts text input into speech that is
outputled through the audio channels. Like SAY, it
uses the translator.library file from the LIBS: direc-
tory to convert the text to phonemes, and the nar-
rator.device from DEVS: to output the phonetic
speech. While SAY takes input only from the key-
board, you mount SPEAK: as a device, meaning it
can lake ils input from any source that can write to
a disk file. For example, you can save a file to
SPEAK: from a w : ord processor or even open
SPEAK: as a capture file for a terminal program.

As with the SAY program, you can adjust SPEAK;
to vary the output's sound. You can change the
pitch and speed of the speech, choose male or fe-
male voice characteristics, and select natural or ro-
bot (monotone) speech inflection. To add a voice
setting, you include it as part of a SPEAK:opts/
pathname when you access the device. For exam-
ple, to listen to a File with a female voice at a pitch
setting of 200, you could use the command:

COPY filename to SPEAK:opts/f/p200

The full list of voice options you can add to the
SPEAK;opts/ pathname is shown below:

P### Set Pilch (### is a number from

65 to 320)

A New Con Man

While your Amiga can talk lo you, it cannot tell
you how lo fix an erroneous command. One of the
major complaints about the CLI environment is
that its console window does not support com-
mand-line editing. If you make a typing mistake in
the first word of a command line, you have to
erase the whole line and start over again.

A new 1.3 device called NEWCON: (similar to
the shareware program ConMan) Finally provides a
console window that not only allows editing with
the cursor keys, but also adds a 2K command-his-
tory buffer. After you mount the NEWCON: device,
(whose handler is located in the file liNewcon-Han-
dler), you can open a CLI window that uses this
new console device by typing:

NEWCL1 \'EWCON:x/y/wm/name

where x and y specify the position of the upper-left

corner of the window, w and h specify its width
and height in pixels, and name designates an op-
tional window name.

With a NEWCOX: window, you can edit a com-
mand line by using the Left- and Right-Arrow keys
to move the cursor back and forth across the line
one spate at a time, or in combination with the

Shift key to take you to the beginning or end of
the line. The up- and down-arrow kevs implement
a command-history feature. Each time you enter a
command line, that line is stored in a 2K circular
buffer. Pressing the up-arrow key retrieves the pre-
vious entry in the buffer, which appears at the
command prompt. Pressing the down-arrow key
moves you forward through the buffer. The shift-
down-arrow combination takes you to the bottom
of the buffer. If you don't want to step through
each previous command, you can use the command
history's search feature. Typing a partial command
line, and then pressing shift-up-arrow, initiates a
search for the last command line that matches the
partial string.

While the original intent of the 1.3 Operating
System was to provide enhanced printer support —
as well as autobooting and faster access for hard
drives — Commodore threw in a few extras. New de-
vices like the recoverable RAM drive, the speech
device, the pipes handler and the rest, increase the
speed and extend the reach of your system at the
expense of only a few commands. ■

Exploring
AmigaDOS 1.3*

In the first episode of info.phile 's "mini-series" on the new version
of the Amiga's operating system, our columnists mill take you
on a backstage touroflJ's new CLI commands.

By Bill Catchings and Mark L. Van Name

* Editor's Note: To get tlie information on ver-
sion 1.3 to you as quickly as possible, the au-
thors have had to use a "gamma " version of
AmigaDOS 1.3. ,4 gamma version is one that
Commodore circulates to developers and a few
other groups so that those groups can see
what's coming and help shake out any bugs. It
is the last unofficial release before the software
hits your dealer's shelves. Most likely the final
version will have the same new CLI commands
as this gamma version, but Commodore still
could make some changes before it releases the
final version. To be safe, when you buy a copy
of version 1.3, plan to spend a few minutes
verifying that everything works as it is de-
scribed here.

THIS MONTH, INFO.PHILE begins a
multi-part discussion of the new 1.3 ver-
sion of the Amiga's operating system.
Version 1.3 offers many new capabilities
and improves many existing ones. There
are new CLI commands, new utilities,
improvements to existing commands and
utilities, a new "shell" that lets you edit
your CLI commands, the ability to make
commands "resident" in memory so
that you can access them more quickly,
tighter integration of the often different
Workbench and CLI environments, and
many other improvements. Just a simple
list of the new features would be exten-

sive — and maybe intimidating!

In this series of columns, we will wade
through that list a piece at a time, show-
ing you the new capabilities and how to
use them. We start here with an overview
of most of the new CLI commands. We
have left two of them, RESIDENT and
XICON, until later when we discuss resi-
dent commands and the integration of
the CLI and the Workbench, respectively.

Setting the Scene for a
Command Performance

The new CLI commands provide a wide
variety of capabilities. That's nice for us
as users, but it makes a systematic pres-
entation of them a bit difficult. So,
please bear with us as we present them
in a relatively arbitrary order.

Three of the commands help you use
and manage your system more easily. If
you have a hard disk, you can use the
LOCK command to protect it from acci-
dental damage. For example, you might
be testing new public-domain software
and want to be sure that no "virus" or
other dangerous program can affect the
data on your hard disk, or you might
want to protect that data from the hands
of your co-workers or children while you
step away from your Amiga for a break.

Its format is simple:

LOCK <drive> ON | OFF
[ <password> ]

lis use is also straightforward: Give the
drive name, then ON to protect the
drive, or OFF to turn off a lock that you
set earlier. You can make releasing the
lock a bit harder by providing the op-
tional, four-character <password> when
you turn the lock ON. Anyone who
wants to turn it OFF must supply the
same <password>. Once you lock a
drive, it stays locked until you either un-
lock it or reboot your Amiga.

You actually can lock parts of a drive
as well as the whole thing. If your drive
has several partitions, you can give the
name of any of those partitions as the
<drive> parameter. This lets you protect
some particularly crucial data on a drive
while leaving the rest open to change.

There is one important restriction:
LOCK only works on hard disks or hard-
disk partitions that you have mounted
with the new version 1.3 Fast File Sys-
tem. This new file system will make your
hard disks run much faster, provided
you mount them with it. AmigaDOS has
traditionally been very slow locating
files, but the new file system will stop
making your hard disks wait on the
AmigaDOS software algorithms and in-»"

AmigaWorld 57

stead let them run at their top speeds.

The Fast File System does not initially
work on floppies. Before Commodore
puts its support software into ROM, how-
ever, it is almost certain to support flop-
pics. Don't worry too much about this
restriction, however; the Fast File System
is so much faster on hard disks than the
old one that you will be very happy once
you move to it.

Those of you lucky enough to have a
battery-backed clock/calendar on your
Amiga will be pleased with the new com-
mand. SETCLOCK, If you have an
Amiga 2000, you have a clock as part of
your Amiga's standard equipment. If you
have an A500, your machine did not
come with a clock/calendar, but several
vendors offer relatively inexpensive
ones. You also get one if you buy Com-
modore's A501 512K Memory Expansion
Module. If, like us, you are working on
the original Amiga 1000, you also can
turn to several vendors for this fairly in-
expensive addition. [For more informa-
tion, see "The AmigaWorld Hardware
Buyer's Guide," p. 48, in the March '88
issue, or "One Thousand One, One
Thousand Two. . .Four Clock Calendars
for the Amiga 1000." p. 18, in the Sep-
tember/October '87 issue.]

SETCLOCK works with the battery-
backed clock/calendar and ihe system
clock/calendar that you can set in Prefer-
ences. As with most CLI commands, its
formal is simple:

SETCLOCK LOAD | SAVE

If you specify LOAD, AmigaDOS sets the
current system date and time to the time
and date in the clock/calendar. If you
Specify SAVE, it goes the other way and
sets the clock/calendar to the current sys-
tem time and date.

This command makes a great addition
to your startup-sequence file. Just put in
the line

SETCLOCK LOAD

and your Amiga will boot with the sys-
tem time set to the clock/calendar's time

and ready to go. You can use the SAVE
option for those rare occasions when
most clock/calendars end up wrong, such
as the days when we change in and out
of daylight savings time.

If you try either form of this com-
mand on an Amiga that does not have a
clock/calendar, your system may appear
to be hung. It's not. Hit RETURN and
you will get the message;

Internal clock not functioning

The last of the three general com-
mands is FF;

FF [ - | - n ]

FF is a nifty little program developed
by Charlie Heath of Microsmiths and in-
cluded in 1.3 with that firm's permission.
It speeds up the way your Amiga handles
text, so that everything from typing files
to flipping between screens with most
editors will run faster.

If you give it the - option, or if you
just enter it with no arguments, you turn
on its faster text handling. It will give
you a line crediting Microsmiths and
then say

Turning on Fast Text

To turn it off, use the - n option. Al-
though you will still see the credit line,
there is no message telling you that it
is off.

. . . Ai\D Now the Plot Thickens

Just about everybody can benefit from
these first three commands. There are
also four other new commands that are
probably most useful to "power" users,
although all of us may want to use them
every once in a while.

The ASK command lets you ask a
question and get a yes/no answer:

ASK <prompt string>

This command is useful really only in
batch files, but it can be very helpful
there. It displays the <prompt string>
and then waits for either a Y or an N
(or the lowercase versions of either of

Table 1. Sample display given by the AVAIL command.

these), and then the Return key. Hitting
Return without entering either Y or N is
equivalent to entering N and then
Return.

If you enter Y, ASK sets the CLI's com-
mand termination, or conditional, Hag to
5, which is the value for a WARNing. If
you enter N or nothing, it sets that flag
to 0, which is the normal termination
value. You can check the value of that
flag in IF statements in batch files. The
IF ERROR statement is true if the condi-
tional flag is 10 or greater, while IF FAIL
is true if that flag is 20 or greater. IF
WARN is true if the conditional flag
is 5 or greater, so you can use this IF
version to test the result of an ASK
command.

ASK is particularly nice when you
want a batch file to check for a user's
confirmation before it takes an action.
For example, if in a batch file you want
to check that a user really wants to de-
lete a file before deleting it, you could
use the following set of CLI commands.
(All except the first command could go
anywhere in your batch file. The first
command, like all .KEY commands, must
come at the start of the batch file.)

.KEY file_name

ASK "Do you really want to delete

<file_name>?"
IF WARN

DELETE <file_name>
ECHO "<file_name> is gone."
ELSE
ECHO "You did not delete

<file_name>."ENDIF

AVAIL is a technical command of a
different sort. It takes no parameters.
You simply enter

AVAIL

and it gives you a breakdown of all of
the memory in your Amiga. In the mid-
dle of playing with these new commands
on an Amiga 1000 with 512K of memory,
we entered AVAIL and got the display
shown in Table 1.

The term "chip" refers to the memory
that your Amiga's three special video
and sound chips can use. For now, this is
the first 512K of your system's memory.
Knowing the amount of available chip
memory can be useful w-hen you need to
know how large an image or sound sam-
ple a program will be able to manipu-
late. "Fast" is the term for all of the rest
of your Amiga's memory, which the spe-*

At long last, (he three mast powerful productivity software
programs for the Amiga " are available in a single economical
package the Critics' Choice'" Productivity Bundle. This
combination of the three most popular productivity programs
provides simple, one-stop shopping for all Amiga owners.

Each of the three programs contained in the Critics' Choice,-
Kind Words'" wordprocessor, Maxiplan 500'" spreadsheet,
and Microfiche Filer' ' database — has been heralded by end
users, magazine reviewers and dealers as the most
outstanding product in its respective category. And now they
all work together as a powerful, integrated system. You can
have all three applications on the screen at the same time,
and move instantly from one to another. What's more, you
can combine work done in one program with work done in
any other.

And All for One.

Purchased individually, these programscostalmost $350. But
together, in the Critics' Choice bundle, all three programs are
available for one low price of $249.95 — a savings of almost
$100! So visi t yo u r local Ami ga dealer for a demonstration of
the three finest Amiga productivity programs available today,
or call (800) 527-7014 for the name ofthe nearest Critics' Choice
dealer.

cial chips cannot use. Because the A10QG
we used has only 512K, AVAIL showed
in all of the Fast categories.

"Available" denotes the memory that is
still available for programs to use, while
"In-Use" indicates the memory that your
executing programs are already using.
"Maximum" is the sum of these two, the
total amount of each type of memory in
your Amiga.

The final category, "Largest," is one in
which only programmers are typically in-
terested. It is the biggest single chunk of
the available memory, which is a limit on
the size of the single largest thing that a
program can put into memory.

The final two commands, SETENV
and GETENV, let you manipulate a new
CLI construct: environment variables. An
environment variable is a container that
can have a string as its value. You can set
this value with SETENV and read it with
GETENV. AmigaDOS commands can
also use environment variables, and
many of them will do so in the future.

AmigaDOS manages environment vari-
ables with the new ENV: handler. Ac-
tually, it will use that handler. Today it
simulates that handler by storing these

variables in a directory in your RAM:
disk (RAM:ENV) and then using the AS-
SIGN command to set ENV: to that
directory.

To set the value of an environment
variable, you use SETENV:

SETENV <environment variable>
[ <string> ]

If you omit <string>, you set Environ-
ment variable> to the null string ("").
You can retrieve the value of any envi-
ronment variable with GETENV:

GETENV Environment variable>
For example, if you entered

SETENV my_data_directory

"df():mydata"

and later typed

GETENV my_data_directory

the CLI would display

dfO:mydata

If you ask GETENV to get the value of
a nonexistent environment variable, it
will respond

Can't get Environment variab!e>

An environment variable thai you
have never set is not the same as one
that you have set to the null string with
SETENV. If you do

SETENV my_data_directory

to set it to the null string, and then do
GETENV my_data_directory

the CLI will display a blank line.

In a future column we will discuss fur-
ther environment variables and how CLI
commands work with them.

These new commands are just the tip
of the AmigaDOS 1.3 iceberg. Next time
we'll crawl a little further down its sur-
face and look at the many improvements
it makes to existing commands.

Until then, try to grab a few spare mo-
ments and play around with this new re-
lease of the operating system. These new
commands and its many other benefits
will make you glad you did. ■

88 Treasure Hunt

A Getaway Weekend for 2

The Clues— Part Two

17. What do Alfred Hitchcock, Cary Grant,
and several American presidents have in
common? Proceed appropriately to an in-
terstate and take Greeley's advice.

18. Pass "Bill's" city and go to a town
whose namesake is famous for a cele-
brated "bon voyage" In 1940. Do what
they did then, and look for a town whose
name is similar to their destination.

19. To find your next route, proceed In a
boreal direction and think of what Bill
Terry, the last of his kind, did during
1930. Proceed in "Mae's" direction, cross
the border, and go to the first major city.

20. Leave town by the "dyslexic prospec-
tor's" route In the same direction and
proceed to the "Cereal City."

21. Go "Dixie" on the first available inter-
state and take it to the city where it
ends. Leave town in the "melted witch's" ,
direction by the route whose number is
the ASCII code for J. Cross a state tine.
Play some rugby (Union) as you proceed:
Score a try and make the conversion.

Add these to your present route to find
your new route. -^

22. Cross a state line. Go to a place where
Thelonius and Art might fee! at home.
From this "origin," travel up the y-axis.

23. Cross the next state tine and begin
looking for your next route. Burglary is
the clue: How much territory did Lou
Brock obtain each time on 938 occasions
In his career? Ride off into the sunset on
the appropriate route.

24. Cross two state tines. Peeling guilty
about all this thievery, go into the dark-
ness and find the place where the person
who ""made you do it" might reside.

25. Return to the route you were on at the
beginning of Clue 24 and proceed In the
same direction. Unfortunately, your com-
puter Is now bewitched with errors. You've
got an "undefined label" and you "can't
CONTINUE." But if you add the Amiga Ba-
sic code values for these, you can find a
new route to get back on track.

26. Proceed down state, pass through a
"ghost town," cross a state line, and
look for salvation in a divine place.

27. You leave this place in a state of ec-
stasy by the same route in the same di-
rection. But soon you're in trouble—
you've run aground, in fact, to put it
slang I y, you're really "in da dirt." But if
you unscramble the letters in that slang
phrase, you'll find your next destination.

28. Leave here by Route 101QQ00O and
proceed in a direction that is an essential
ingredient of beer minus the first letter.
Cross a state line and look for a town that
Is also the name of a book chronicling the
exploits of Steve, Leo, and Moil,

29. Mimic birds in springtime and proceed
from here on a tittle two-bit road. To find
your next route, double your stake and
go back to making beer,

30. To find your next route, begin at
"square one" for the first digit. Add the
square root of four to the first digit to get
the second digit. Add the cube root of
eight to the second digit to get the third
digit. Proceed in the direction Scott ex-
plored. Your next destination is an "on-
line" city that is also the end of the line,
and appropriately the end of Part Two of
the Treasure Hunt. Wait here until next
month for further instructions.

from p. 22

If that isn't enough, ail excellent com-
panion to the Wrap-On feature called
LUM shines light across the surface-
mapped brush to give it a real three-di-
mensional feel. The LUM controls allow
you to set the intensity and direction of
the light source, and although setting the
controls takes some getting used to, the
result is well worth it.

Blend, found under the Mode menu, is
similar to Digi-Paint's Tint mode in its
ability to overlay colored light on the
area being painted. The transparent
wash subtly alters every color beneath it.
Photon Paint takes this one step further
by supplying a "Set. . ." Blend control
window that lets you determine the tint's
intensity, as w r ell as the degree and direc-
tion of gradation and dithering. By ma-
nipulating the controls in this window
you can create a color overlay that is
nearly invisible at the edges, and intensi-
fies toward the center (or any other
point), until it's nearly opaque. The flexi-
bility and versatility of this control is al-
most infinite, and it works with any
brush or drawing tool.

An Integral Part

Photon Paint i.s excellent. It's probably
not the only paint program you'll ever
want, though. The developers have incor-
porated all of the basic tools to make
Photon Paint a true HAM-paint program,
but because it is HAM, there are minor
problems. When you choose a standard
brush from the toolbox, you can't see it
on screen until you actually start paint-
ing. If you are involved in a precise op-
eration and you're using a large round
brush, for example, you see only a cross-
hair on screen until you press the mouse
button — and then it's loo late. Another
HAM-related difficulty is speed. Photon
Paint claims real-time operation of free-
hand drawing tools, but if you move the
brush swiftly, the stroke lags behind the
cursor. In fact. Photon Paint is overall a
bit slower than I expect a paint program
to be, both in terms of operations and
calculating.

Photon Paint is an essentia! part of the
ideal Amiga graphics studio. For starting
a picture from scratch (no digitizing or
image imports) I'll still want DeluxePainl
II's speed and practical tools and I'll rely
on Digi-Paint for its colorizing tech-
niques and Rub-through feature. Photon
Paint is the program I'll use to bring all

the elements together and realize the full
potential of Amiga graphics. If only it
would print out on canvas. . . .

flickerFixer

Visionary improvement for the
Amiga 2000.

By Douglas E Watt, PhD

I WAS SO impressed by the A2000's nu-
merous other virtues that at first I over-
looked the small video slot in the back-
light corner of the motherboard. Thank-
fully though, MicroWay did not. They
have employed this slot to literally trans-
mute the Amiga's video display, via the
FCC Class B-approved flickerFixer video
buffer card. flickerFixer banishes hi-res
flicker and visible scan lines. The result?
Well, compare the difference between
night and day.

flickerFixer takes existing video out-
put, buffers it, then adds the output
from the next set of 200 scan lines if the
output is interlaced (or fills in the other
200 lines with the same information if
not), and sends that 400-line composite
out at a 60Hz rate. By contrast, the stan-
dard interlaced display refereshes at a
rate of 30Hz, which is inadequate given
that the screen generally decays in one-
fiftieth of a second. flickerFixer does not
alter the stock Amiga video signal in any
way, and except for the fact that you can-
not use a genlock concurrently, it is com-
pletely transparent. It even allows you to
use the normal video output and moni-
tor simultaneously.

The combination of no scan lines in
any mode and the total absence of inter-
lace flicker — even in stark black-and-
white high resolution — is impressive.
flickerFixer is a help for desktop pub-
lishing and CAD-CAM Computer-Aided
Design, Computer-Aided Manufacturing)
applications, as well as hi-res and HAM

(Hold-and-Modify) interlace painting.
flickerFixer makes working in the nor-
mal 640 x 200 Workbench mode more
enjoyable because it fills in the scan lines
to produce solid characters, thus reduc-
ing eye strain. It is leagues ahead of the
sunglasses antidote and the various
screens that fit over your monitor, not
only in effectiveness, but in price as well.

The card lists for $595. Because flicker-
Fixer's near-industry-standard scan rate
of 31.5MHz is not compatible with the
Amiga 1080, 1084, and 2002 monitors
(which run at about 15MHz), you'll also
need a good multisync or VGA monitor,
which cost between $425 and S800.
(flickerFixer's designer opted for the
high scan rate because the lower rate sig-
nificantly limits resolution.)

With flickerFixer and a VGA or multi-
sync monitor that has a reasonable ad-
justment range, you can get a full
Workbench screen of 740x470 pixels
(something that is hard to do with an
Amiga monitor) using the public-domain
program MoreRows. On the flip side,
you may not be able to get the stock
Amiga output to cover the full face of
some monitors unless you're willing to
experiment with the potentiometers on
the internal monitor board. If in doubt
about the compatibility of flickerFixer
with a monitor, call MicroWay.

If you can't afford to buy it, I wouldn't
recommend trying flickerFixer; it will
only leave you depressed when vou have-
to go back tf) your old display.

Summagraphics is no newcomer to the
graphics tablet field, having produced a
variety of such devices over the last feWi
years. Until recently, however, Amiga
owners were out in the cold if they
wanted a Summagraphics tablet, because
no software drivers were available.
R&DL Productions now packages Sum-
magraphics MM series tablets with
Amiga drivers for both freehand-drawing
and CAD (Computer-Aided Design) ap-
plications in the form of AProDraw.

The tablet, finished in Amiga-coordi-
nating beige vinyl, comes parceled with a
stylus for drawing applications. A four-
button mouse with clear-plastic cross-hair
sight is available as a S50 option for
CAD users. (Note: For the purposes of this
review, Gary I.udwich, our graphics-tablet ex-
pert, tested AProDraw on his A 1 000. Using
the CAD mouse, Lou Wall/ire Own evaluated
it from the CAD perspective on his A2000.)

Double Double

Xot only is the tablet available for two
different applications, but in two sizes as
well. You need plenty of desk space to
accommodate the 16 x Id-inch tablet: the
smaller one is 9x6. Each unit comes
with its own power supply, and hooks up
to the Amiga via the serial port (al-
though providing no pass-through con-
nector). The A1000 requires a gender
changer for connection (which R&DL
thoughtfully provides), and the cable
plugs directly into the A500 and A2000.
While the large connector presents no
problems on the A500, you must remove
one of the audio plugs to accommodate
it on your A2000 (a minor problem un-
less vou need both sound channels).

The SummaDriver software, which in-
tercepts mouse signals, is easy to install
via Workbench or CLI. It provides four
utilities, including a configuration table
(that allows you alter the tablet's aspect
ratio) and three working modes: default
(640x2110), hi-res interlaced, and low-res
(320). Those with non-standard Amiga
systems, particularly third-party moni-
tors, will need these configuration
choices, but most people won't. The
package comes optimally configured for
the Amiga and as such it's pretty much a
piug-in-and-use system.

AProDraw's sliding easel back is
unique and particularly useful: it allows
you to set the angle from fiat to about
30 degrees. Unlike the Easy] tablet, how-
ever, the rectangular version works only

in the landscape (horizontal) orientation;
there is no portrait (vertical) option. The
larger tablet, of course, works in a
square format.

On the Draw

Offering a two-button wired stylus with
electronic pickup, AProDraw occupies a
previously-unfilled niche. The tip of the
stvlus (unctions as the left mouse button;
pressing it against the tablet engages it.
You can replace the nylon tip with a ball-
point-pen refill, tape a piece of paper to
the tablet, and work in the conventional
manner. For mativ artists ibis is an im-

The 16-inch tablet with serial connector,
stylus, and CAD mouse.

DOrtant consideration — it's all a mailer
of where you look while you draw. The
right mouse button is on the barrel of
the stylus.

AProDraw also works in the single
handed style to which mouse users are
most accustomed. Like the mouse, the
on-screen cursor will follow the relative
position of the stvlus as long as it is in
close proximity to the tablet. With
DeluxePaini II (Electronic Arts), cursor
and screen action were smooth and well
controlled. (R&DL says that the unit per-
forms fastest with DeluxePaint II ver-
sions 2.1 and later.)

Can You do the CAD/CAM?

The four-button mouse cursor is suitable
for precision CAD work. The crosshair
function lets vou digitize drawings di-
rectly into your CAD program by over-
laving them on the tablet. Two of the
buttons work as the standard mouse but-
tons. The other two are inoperable;
they are not needed in the Amiga
configuration.

M2Am iga is a software development system for Modula-2
based on an extremly last single pass compiler. It is fully
integrated into Amiga Workbench and is easy to use from
CLI or Workbench. It runs on all Amiga models with a
minimum configuration of 512k RAM and one disk drive.
M2Amiga has been developed specially tor the Amiga
and therefore optimally supports the features d( this
unique computer.

- Produces optimized native code. Full support of latest
edition of Modula-2.

- No intermediate code needed for library calls and para-
meter passing.

- Supports FFR 32/64 bit IEEE reals formats, even mixed
within the same program,

- Easy access to registers, allows the insertion of inline
code.

-Full interface definition to the Amiga's operation
system.

-The best runtime system currently available on the
Amiga. Opens and closes all used libraries, captures all
GURUs and releases all used resources after program
crasn or termination. Routines for System requesters
enable user interface consistent with the Amiga's
Intuition.

- The emacs base,d editor places the cursor on compilation
errors and explains tliem in full text.

- Links in just a few seconds. Stand-alone applications
are com pact and last.

- Besides the handy manual, an introductory guide to
Modula-2 is included.

- Demo programs show the use of various features of the
Amiga.

- For professional program development special utilities
are available.

+ Source Level Debugger, the new way of debugging

your programs.

IntroCAD (Progressive Peripherals),
LogicWorks (Capilano Computer Sys-
tems), PCLO (SoftCircuits), and X-CAD
(Taurus-lmpex), Each worked as ex-
pected, and movement seemed precise,
although one small quirk did manifest it-
self. On several occasions the driver be-
came inactivated and control passed
back to the regular mouse. This was not
fatal, as it was possible to save the work
in progress, exit the program, and restart
the tablet. What caused this, however, re-
mains a mystery; no particular keystroke
combination or specific mouse activity
seemed to be responsible for triggering
the driver problem.

Test Drive

AProDraw is potentially valuable for
Amiga artists and CAD professionals, but
you might do well to try il with your
software, especially if yours is an older
package. Because so many more personal
and ergomctric considerations are in-
volved with tablets than with other hard-
ware pieces, you need to test drive every
available unit before making a purchase
decision. The R&DL packages are excel-
lent systems — well designed and smooth
functioning. Make this system a "must
try" if you are considering such a device.

Impact A2000 SCSI/RAM
Hard Disk Controller

One slot does double duly.
By Louis R. Wallace

TWO OF THE most popular expansion
devices for the Amiga 2000 are memory
cards and hard drives. Greal Valley Prod-
ucts addresses both these needs on one
card by combining a hard-drive control-
ler with expansion RAM on the Impact
A2000 SCSI/RAM board.

The card I reviewed was populated

with one megabvte of RAM, but you can
buy the Impact board unpopulated and
add memory in 51 2K increments. A
jumper, which you must set to the
propei RAM configuration, is included.
Both the RAM and controller auto-
configure.

One connector is available for an in-
ternal SCSI (Small Computer System In-
terface) hard drive, and an external,
Macintosh-pin-compatible connector will
join up to seven SCSI devices. The board
also has empty ROM sockets to which
you can add ROM chips containing
the 1.3 operating system and 1.3 Kick-
start. With 1.3, your A2000 can bypass
Workbench and boot automatically
from vour hard drive — an essential for
those who believe the Amiga must
autoboot to be considered a "real
computer."

Hop On Board

Installation is simple; just open your
A2000 and plug the board into any
empty slot. The 28-page manual de-
scribes the procedure fully but lacks dia-
grams, If von do not have experience
installing hard drives, you may want to
get help.

Once the controller is in place, you
must prepare the drive for use. The sup-
plied software does that for you; it pre-
pares and formats your bard drive, and
then creates a Workbench disk with the
proper Mountlist and a startup-sequence
to activate the hard drive and turn con-
trol over to it on bootup. While this
system works fine for AmigaDOS, the
software does not contain options for
preparing the drive with the 1.3 Fast File
Svstem.

One essential characteristic of any de-
vice you plug into your Amiga is com-
patibility with currently installed
components. When I first set up the Im-
pact board and 40-megabyte Miniscribe
SCSI drive, I had problems. (I have a
two-meg RAM board, a Commodore
A2090 controller, and a Seagate S'1'251
40MB hard drive.) 1 was able to install
the SCSI drive properly, and the RAM
auto-configured without a hitch, but
when I attempted to use both the A2090
and the Impact board, a variety of read
errors on the SCSI drive resulted.
Worse yet, using any RAM-intensive
software brought me face to face with
the Guru. The engineer at Great Valley
Products determined that I had an early*-

version of the board — one containing
old PAL chips thai had a history of in-
compatibilities with the A2090 (and
perhaps Commodore's two-meg card,
too). I exchanged it for a replace-
ment card that worked without further
difficulty.

In spite of my problems with the origi-

board a powerful addition to my Amiga.
With the autoboot ROM chips it will be-
even more useful. If you are shopping

LV Backup

Quarterback

saf-T-net

Software insurance for your hard
work and hard disk.
By Carl Mann

SO YOUR NEW hard disk is up and run-
ning. You're zipping through work that
once bored you to tears with disk swaps
and gronking drives. Isn't it wonderful?
Sure is, as long as nothing goes wrong.
By the way, how many days of work can
you recreate from memory?

A backup utility insures your work. It
will back up your hard drive's contents
to a set of floppies, and restore the in-
formation to the hard disk should disas-
ter strike. The right backup can make
the critical difference between a tempo-
rary glitch, and being out of business for
hours or even weeks.

I tested LV Backup (MKSoft),
QuartcrBack (Central Coast Software),
and saf-T-net (RSN Software). All three
perform full or partial backups and res-
torations (you can dictate that partial op-
erations be performed only on files that
have changed since the last backup).
Each starts from the Intuition interface.

and none are copy protected. Also, all of
them back up and restore from a variety
of AmigaDOS devices in addition to
hard disks. Each will prompt you for the
right disk if you try to feed it the wrong
one during a restore cycle, and all refuse
disks produced by either of the others.
The commonality ends there though.
The accompanying chart will give you an
idea of the differences.

LV Backup; Simple Does It

LV Backup offers by far the simplest
user interface of the bunch. The restore
option is pretty pokey, but if you need to
use it more than once or twice in a year,
there's something wrong. At any rate, the
error messages are easy to understand
and the huge busy indicator is impossi-
ble to miss. The tiny manual is clear,
brief, and easy to use, but it does lack an
index.

LV Backup will back up from any
Amiga device except df():, which it re-
serves as its "work drive." This, com-
bined with the fact that no other Amiga
work can be done while the program is
running, may seem odd. In defense of
this system though, backups are usually
the last thing I do at the end of the day,
when I don't feel super productive
anyway.

LV Backup offers a substantial bonus:
a full-featured text editor. You'll gladly
discard the Amiga ED for MkSoft's
TexlEd. In addition, there's a spiffy
printer spooler complete with C source
code, an excellent version of the classic
Go-Mo-Ku game, and an elegant title-bar
clock. All in all, a lot of software for a
small price.

As we go to press, version 5 of LV
Backup, the Workbench 1.3-compatible
update, has arrived. Version 5 offers no
speedier backups and restores to RAM:,
but because it takes advantage of the 1.3
Fast File System (the only apparent
change), a 30-tninute backup-to-floppy
cycle under 1.2 is reduced to about
seven minutes. As a result, the fact that
LV Backup ties up dfO: is a lesser consid-
eration. My hat is off to MKSoft;
I'm sure the other development houses
will offer similar upgrades in the
future.

QUARTERBACK: VERY FRIENDLY

dards in user friendliness. The program

configuration error and retry without a
lengthy menu cycle. saf-T-net's activity-
log is highly detailed. All error messages
are included, and are listed in order of
occurrence.

On the downside, saf-T-net users can-
not do partial restores and backups by
clicking on a directory name in the dis-
play window. Instead, all files are dis-
played in a single window with their full
pathnames, and you must select each in-
dividually. This, however, means that no
selected files are ever hidden from view.

saf-T-net disks must be copied with the
special utility provided. Attempting to
use the AmigaDOS DiskCopy command
or Intuition will fail.

Marking Time; The Speed Contests

Using the Amiga RAM: device on my
one-megabyte system to produce univer-
sally meaningful results, 1 timed each
product as it performed backup and re-
store operations between RAM: and the
floppy drive. I conducted three separate
runs, and then averaged the numbers
for each. My test disk contained 140
files, totaling approximately 680K of
information.

The two leaders showed no substantial
difference between backups to unformat-
ted or preformatted disks. The first pro-
gram to cross the backup finish line was
QuarterBack, with an average time of 51
seconds. LV Backup came in only four
seconds behind at 55 seconds. saf-T-net
trailed with a time of two minutes, 40
seconds for unformatted disks, and a
minute, 45 seconds for preformatted tar-
get disks.

QuarterBack, that all-around speedster,
won the restore contest too, with a time
of one minute, 20 seconds. saf-T-net took
the red ribbon with one minute, 50 sec-
onds, and LV Backup clocked in at an
even three minutes.

Each of the three programs will appeal
to a different user. LV Backup's simplic-
ity will appeal to anyone who wants to
get the job done without fussing around.
QuarterBack will be the choice of those
with slight hackerish tendencies. Al-
though the program broke under heavy
use, its configuration and command files
and multi-floppy access abilities save
time. saf-T-net is a system developer's de-
light; it speaks computerese, but its pow-
erful options require extra caution.

All three of these programs do the job
they set out to, and none has serious
bugs. Your choice will depend on how
much of a hacker you consider yourself
to be, and how much flexibility you need
from a backup utility.

MAIL ORDER MADE EASY!

AmigaVvorld knows the meaning of trie term "Valued
customer", therefore we have put together a few guide-
lines for our customers to use when ordering from mail
order companies advertising in our magazine. These
are only guidelines, so if you wish to find out specific
laws in your state, we suggest you cail your State At-
torney General's office.
AmigaWorld does no! intentionally run advertising that is not legitimate. However, occa-
sionally there is the "bad apple" and we have to deal with the problems created by such a
company. We will be the lirsl to tell you if a company cannot meet its obligations or stand
by its word. Should you have a problem with one o( our advertisers, write to:
Lisa LaFleur, Customer Service
AmgaWorid Magazine, 80 0m &, Peterfcorough, KH 03458
Include in your letter a description of the problem, your name, address, telephone num-
ber, copies of any cancelled checks, credit card statements, and the dollar amount involved. We
will act on your behall in contacting the company to help you get your particular problem reserved.
We do not make any guarantees in the results, but we will try.

Should you wish to inquire as to the reputation of a company we can provide objective
and up-to-date information. Please call Lisa LaFleur at 1-800-441-4403.

The foilowing is a listing of basic guidelines to use when ordering mail order either
through the mail or over the telephone.

1. Know the advertiser:

If you haven't seen this company advertising tn the past, call the magazine and inquire,

a. Occasionally advertisements will look similar, almost as if one wBre a direct copy of
the other.

b. Be sure you identify the company from which you prefer to buy.

2. When ordering by mail;

a. Fl?l out the order form completely and double check for errors.

b. Keep a copy of the order and the advertisement. Make sure you have a telephone number
for both the magazine and the advertiser, Note the date you mail the order.

c. K using a credit card, check with your credit card company on their policy (or disput-
ing charges.

d. If an item is backordered, the company must notify you by mail within the advertised
shipping time period or 30 days. If the item is not shipped 30 days after the first
notification, they must notify you again, and every 30 days after that, giving you the opportu-
nity to cancel your order.

When ordering by telephone:

a. Fill out the order form completely, double check for errors and keep it next to the
telephone when calling in your order.

b. Write down the date you call, the name of the person taking the order and ask rf it is
an order taking service or if the person works directly for the company.

What to look for on the ad and what to ask lor on the phone:

a. Check the prices of the items you are ordering. Ask if the item is on sale. Ask about
quantity discounts, if you are ordering more than 1 or 2 items.

b. Ask about shipping charges. How are the items shipped? Do you have a choice? Who pays
for shipping? How long will it take?

c. If items are damaged in shipping or incorrect, ask who pays for return shipping.

d. If an item is incorrect or damaged, ask if you need an authorization number or form
to return the item.

e. Ask if there is a restocking fee when an incorrect or damaged item is received,

f. Ask if the item is in stock and the quantity available.

Take your time and do some research on several companii
before ordering. Mail order can be easy, safe and
save you quite a bit of money when you do it right.

GAME SHORTIES

Return to Atlantis

AS AN EXPKRT marine biologist of the
Foundation, your goal is to preserve the
oceanic ecosystem. You must work
through 11 linked adventures, becoming
further attuned to your subaqualic envi-
ronment, and eventually fining together
the pieces of an elaborate plot.

You receive half your mission state-
ment from a top Foundation agent; the
more important part you read in the
manual. From your base on Isle Perdida,
you proceed to the Sea Thief Cafe where
you meet five characters. You can bribe,
threaten, or plead with them, and at least
one will reveal useful information.

Aboard your ship the Viceroy, you get
further instructions through ART, the
Advanced Robotic Transcoordinator that
receives messages and scans the ocean
floor. You'll also find a Medical Beam,
capable of restoring your failing health,
and a Gear Room filled with equipment

Once you dive, the real work begins.

On screen, you see yourself, donning
scuba gear and ready to swim, sur-
rounded by sea creatures and plantlife.
The mouse seems to be the easiest way
to control your direction, but you can
opt for a joystick or the keyboard. At the
bottom of the screen is a menu bar,
from which you can select maneuvers.
You can swim, scan, attack, use equip-
ment, and order ART to beam things up
to, or down from, the Viceroy. You cati
also command RUF (Remote Underwater
Friend), your search robot.

Unfortunately, the game stops just
short of excellence. The mechanisms
provided for steering your diver are awk-
ward, and generate sluggish response.
This may reflect the difficulty of moving
underwater, but often the diver doesn't
react at all. Using your weapon is diffi-
cult too, and commanding ART is some-
times much work for little payoff. More
importantly, the requirement that you
complete each mission in order can be
frustrating. While some assignments are

easy to solve, others are difficult — mainly
because of weak or ambiguous instruc-
tions. Episodes four, seven, and ten took
me several attempts (I eventually called
Electronic Arts' hint line): T would rather
admit I'd failed and move on.

What the game lacks in these areas, it
makes up for in concept. The missions
take you through an intriguing mystery.
Unlike most computer games, this one
demands ethical behavior. Your missions
are for the sake of ecology, and if you
fail to preserve life you are reprimanded
and must replay the episode. At limes
it's a bit heavy-handed, but overall a re-
freshing difference.

Mechanically, Return to Atlantis suf-
fers a little, but graphically it is very
good, and conceptually it's superb.
Mildly addictive, it also offers novelty for
those interested in the progress of com-
puter games. {Return to Atlantis, Electronic

WHAT HAPPENS WHEN
high-speed liquid crystal shut-
ters allow vour computer to
control what each of your eyes
sees individually (at 30 frames
per second)? You peer into an-
other dimension — the third di-
mension — of video graphics.
Unlike ordinary red-and-grcen
3-D glasses, the X-Specs 3D
package ($124.95) includes hi-
tech shades, software, and a
mouse-port interface. Look
for supporting programs, and
gel all the 3-Details from

Amicore International has
three solutions. The Transves-
tor 1000 ($19.90) hooks up to
the A 1000 and lets you hook
up products designed for the
A500 and A2000 parallel
ports. Transvestor 2500
($19.90) does just the opposite:
it connects the A500 or A2000

to most AlOOOstvle peripher-
als, and the plus in Transves-
tor 2500 Plus ($49.95) means

yon get complete compatibility
with all A1000 devices, and an

Rah-Rah for Ram

TWO, FOUR, SIX, eight; how
manv megabytes will vou take?
If you need an upgradable
memory expansion board for
your A2000, then shake a
pom-pom for ProRAM 2000.
Because you can add to the
S399.95 unpopulated board in
two-meg increments, it is com-
patible — in six-meg form —
with the A2088 Bridgeboard.

ProRAM 2000 uses one-mega-
bit DRAM (instead of 256K.)
chips, and includes a dynamic
RAM controller. The auto-con-
figuring boards are compatible
with AmigaDOS 1.2 and 1.3
auto-config software. For more
information talk to the team
at Progressive Peripherals, 464
Kalamath St., Denver, CXI
80204, 303/825-4144.

THE LATEST ENTRIES from
Great Valley Products are ex-
pansion devices for the A2000.

The auto-configuring,
Hayes-compatible Impact
Modem2400-1 fits into an
A2000 slot, and supports data
rates of 2400, 1200, 600, and
300 bps, as well as Bell 103,
2I2A, and CCITT V.21, V.22
(A and B), and V.22bis stan-
dards. It also incorporates a
digital signal processor for re-
liability, and because the cir-
cuitry automatically selects a
communications standard and
baud rate to correctly match
the remote modem, all you
need to do is dial (touch tone
and pulse are both supported)
and send.

A bard-disk on a card, the
Impact Autoboot Hardcard is
a combination ANSI X3T9.2-
compatible SCSI controller
and 20- or 45-megabyte hard
disk. The hardcard auto con-

figures the controller and
leaves your peripheral bays
free. It also offers two sockets
for autoboot driver ROM/
EPROMs, and supports the
new 1.3 East File System. An
8K disk buffer is provided for
16-bit wide DMA data
transfers.

Another Impact SCSI/RAM
Hard Disk Controller, this
time with two megabytes of
memory, is available, too. Di-
rect your questions about the
RAM/Controller board ($360
unpopulated), the 20-meg
($599) or 45-meg (S850) Hard-
card, and the Impact Modem
(S249) to Great Valley Prod-
ucts. PO Box 391, Malvern,

DEALER INQUIRIES INVITED

HELP KEY

While the other editors were out in the sun, Lou Wallace put his sunglasses
to good use, staring at the computer screen and answering questions.

Keep Still

Q: lam thinking of using a VGA

monitor, such as the Zenith ZCM-
1-190 or the IBM Color Display
H5I3 with my Amiga. Are they
Amiga compatible? 1/ so. will they
rid llii' interlaced mode of the trou-
blesome flicker?

A. Rahman
Binghamton. NY

A: 1 ani iiol sure about Amiga
compatibility with the specific
monitors vou mentioned, bul
IV chni cal Editor Bob "Bit-
Plane" Ryan i.s using an NEC
MultiSync monitor (which is
VGA compatiabie) with his
A2000. By itself, the monitor
will not still the interlace
flicker, but you can use it in
conjunction with the flicker-
Fixer board from Microway
(see review, p. 04). which does
completely remove the inter-
lace flicker. The results are im-
pressive, to say the least.

If you're willing to wait.
Commodore is working on a
sei of Bi-Sync (dual frequency)
monitors for use with the four-
color, 640x400 non-interlaced
mode on version 1.4 of the
Amiga operating system. Nei-
ther the monitors nor 1.4 will
be available before next year.

Subroutine
Subterfuge

Q: / am writing an Amiga Basic
program thai makes heavy use of
Amiga Basic's subprogram module
feature. The main program re-

By Louis R. Wallace

quires a tot of accuracy in its float-
ing-point math, anil I me the
DEFDBL declaration to pace it to
Use double precision as the default
for most of its variables. However,
there are some portions of the pro-
gram that da not need this preci-
sion, but do need to he executed at
lop speed. These routines are
within the subprograms, and I am
using single precision and integer
variables here. The problem is that
many oj my subprogram variables
somehow end up as double preci-
sion! What is even more confusing
is that they are not SHARED
variables, and are supposed to be
completely local to the subprogram!
Am I crazy, or is this a bug in
A m iga Basic?

B. Cobham
Stillwater. OK

A: No, you are not crazy, and
in fact my guess is that you
have discovered a little known
quirk in Amiga Basic. You are
quite correct when you say
thai subprogram variables are
complclelv hidden from the
main program unless specifi-
cally indicated otherwise with
a SHARED variable statement,
but I think your problem lies
not within the subprogram,
but rather outside in the main
calling program. You men-
tioned you have used the
DEFDBL declaration to force
a range of variables to double
precision. This is most likely
the source of the problem.
These variable-type declara-
tions apply not only to your
main program, but also to the
subprograms themselvi s. So, it

vour program has the
statement

DEFDBL ae

forcing double precision on
all variables siarting with let-
ters a through e, any variables
within the subprogram thai
meet these requirements will
also be double presiciou unless
explicitly stated otherwise. The
problem arises if some of your
variables in the subprograms
are expected to be the default
type of single precision and
begin with one of the letters
in the a through e range. This
problem is true for all five
types of variable declarations.
DEFDBL DEFSNG, DEFSTR,
DEFINT and DEFLNG. And
the converse is also
true. . .meaning tvpe declara-
tions within a subprogram af-
fect the en! ire program, not
jusl the subprogram they are
found in.

The solution is to avoid
ihese global-type declarations
if possible, or if that isn't feasi-
ble, add a type-declaration
character to the end ol any
variable whose type can be

Table 1. Declaration characters.

critical to the successful execu-
tion of vour program. Each
type of variable used in Amiga
Basic has a distinctive trading
character, indicating that ibis
variable (and only this vari-
able) is to be considered a spe-
cific type of data. (See fable 1
for a list of the declaration
characters.)

Perhaps you know these dec-
laration characters but find it
more expedient to use the
1)1- ".[■" I , i PL ( ommaud. Vou
should get to know them and
use them whenever possible,
as they can make your pro-
grams more efficient and
meaningful. And. if you must
use global-type declarations
such as DEFDBL vou can use
the declaration characters
to override the global
declaration.

sake of my kids (who are not as
well versed in English as I am).
Are you aware of a French-based
Amiga publication that I could use
as my second source of Amiga
information?

M. Gassend, PhD
Madagascar

A: You are in luckl 1 have just
recently heard of a new
French-language publication
that caters to the Amiga.
Called A-\'ews, you can write
for more information at the
following address:

A-News

Analog Spice

Q: In the February '88 Help Key,
Mr. Castellotti asked about analog
circuit simulator software for the
Amiga. One of the most important
is SPICE, available for the IBM
PC. The educational version in
publicly distributed. Because
SPICE can be used without graph-
ics, I assume the Transformer IBM
emulator software would let you
run it on the Amiga. If Mr. Castel-
lotti has a Bridgeboard, he could
run it without any problems. For
more information, you can write to
SPICE's manufacturer, MicroSim
Corporation, at 23175 La Cadena
Drive, Laguna Hills, CA 92653.

J. Dudley
Amherst, MA

A: Thanks for the information.

Half for Demise

Q: / recently tested my Amiga
WOO for the ability to use Extra
HalfBrite Mode. It failed Die test!
Can I update my graphic chips to
support it?

A. C. Heismann
FPO Sun Francisco, CA

A: You can take your com-
puter to an Amiga service cen-
ter and have them replace the
chip, or if you are technically

inclined, you can do it your-
self. Be warned that opening
your computer and replacing
components voids your war-
ranty, and if you are not very
careful, you could end tip
damaging the computer. The
chip you need to have re-
placed is called Denise. Ac-
cording to Commodore, Extra
HalfBrite Mode is supported
by all A500 and A2000
models, and all AlOOOs made
after January 1986. These all
have a revision 6 or greater
Denise chip, so your Amiga
1000 must have an earlier ver-
sion of this chip. (My A1000
doesn't support EHB mode ei-
ther, which is not surpris-
ing — it was purchased in
September 1985.) According to
the A1000 service manuals, the
part number for Denise is
C252126-01.

The Russian 33

Q: / am using ProWrite 2.0 with
my Seikosha SP-I80AI printer
and the Amiga 500. My father
wants to write letters in Russian
for international correspondence.
The problem is that the Russian
alphabet contains 33 characters
and English has 26. Is there a pro-
gram that will allow me to create
fonts larger than 26 characters,
perhaps using some sort of ALT or
CTRL key combinatioti to access
the extra seven characters?

M. Kerezman
(huega, NY

A: Yes. The program is called
FED (Font FDitor), and you
can find it in the Tools direc-
tory (drawer) on your 1.2
Amiga Extras disk. FED will al-
low you to create fonts of var-
ious sizes and shapes,
including Russian. The default
range is from 32-127 ASCII,
but you can change it to any
range within 0-255. By using
the characters above ASCII
127, you can define the non-
ASCII characters to anything
you wish. ■
